Thought I would post another update photo of the collective project now that 80% of the main set components are now assembled.

Just the Carrier No. 4 delivery to sort out now.

Default 52-Set Sender Modification Instructions

This is almost a simple topic as only one modification shows up in the listing I have for the Sender. Naturally, it is Modification No, 1, for the installation of the modification card holder.

This is where the 'almost' above comes in.

The instructions state a metal plate is to be removed from the left rear corner of the chassis, holes to be drilled into the plate, the holder attached and the plate returned to its position on the chassis. Problem is, there is no metal plate on the chassis in that location, either on the rear or left side of the chassis. I checked the Sender chassis I have and all the photos of the Sender in the manual. No such plate.

There is no room at all on the top of the chassis to mount a card holder and I could see nothing anywhere when looking through the chassis. Curiosity got the better of me finally and as a last resort, I carefully turned the chassis over to have a look at the bottom. There it was, as per the attached photo. And there was a modification card inside stating the modification was done in 1947, but no mention of the Shop where the work was done.

I have not really detailed out the parts sequence for restoration work on this project just yet. The Carrier No. 4 still needs to be looked at up close once it arrives, but other than that, all I know so far is the first priority will be to finish work on the two receivers. That work is already three quarters completed, so best follow through with it.

My suspicion is the Supply Unit may end up being the last item tackled. I still have two single conductor connector cables to find for the main set and until they are found, I do not want to risk damage to the Sender, Supply Unit or both by ad hocing anything foolish. So buying more time by restoring the supply last makes sense from that perspective.

I was initially hoping the panel of the Supply Unit could be polished back down to the right shade of paint patina to blend in with the two receivers, but now that I have cleaned the grime off and had a closer look, that will no longer be possible.

First, too much paint is completely gone from the bottom of the panel. Nearly an inch, and in that same area, the bottom inch of the Receiver Vibrator Supply Module has been bent inwards just enough that it will have to be tooled carefully back to straight. I don’t think there is enough ‘careful’ available in the paint to prevent it from spalling off when that work is done.

The final factor in deciding on a complete restore of the supply panel was the discovery of just how incredibly sloppy the decal application work was during its 1966 shop refurbishment. Take a look at the attached factory photo of the supply decals from the manual, and compare it to the work done on this supply. Yikes!

I think some good water transfer decal software is on the horizon for me at some point.

I recall reading about creating water transfer deals by printing. One issue is with printing white - most printers rely on white paper rather than actually printing white so you either need to find one of the rare printers that deposits white to the page or print on transfer film that has white background (and cover every scrap that you don't want to show white (including around the edges)).

Hi Grant.

Yes. I suspect a bit of research will be involved when I get to that point. And very likely, a new desk top system.

Something else I just noticed reading your response. The decals used in the 1966 rebuild have a similar overall size to each of the originals, but there is a lot more black surrounding the words. The decals in the manual photo are a match in surround size to the decals on my receivers, and the Sender.

Hmmm. I think I will have to put the black light on the Supply Unit and Sender tomorrow and see what, if anything glows, and in what colours.

A really quick Google says that waterslide "paper" to suit either laser or inkjet printers exists with either white or clear background (i.e. four different types of "paper").
At one time there were dye sublimation printers made by ALPS that could print white but they seem to be out of business...
There are listings on ebay for refurbished Alps printers for waterslide printing - eg. https://www.ebay.ca/itm/Refurnbished...IAAOSwRJ1Zn~QZ There are also results for Windows 10 drivers for the Alps MD-1000. However, specialized orphans can be relatively expensive and the consumables can also be out of line compared to more widely used and current product.

The last major piece of this project arrived yesterday afternoon via FedEx. Quite an impressive beast when you get it unpacked!

Main plan for it at the moment is a basic clean up of all the years of dirt and grime accumulation. Sadly, it underwent a 1960’s era repaint in which all original finish was stripped and NATO green applied. Like the Remote Receiver Case I found, even the inside of the carrier was painted. In the Remote Receiver Case, the paint inside was thin enough the two grounding springs in the upper back of the case were still capable of grounding the case to the chassis of the receiver. The paint job on this Carriers No. 4, however, is so thick inside, I don’t think any of the six grounding springs could work properly again.

Once cleaned, I must read up in the manual about the correct way to reinstall the three components. Jacques Fortin brought this point to my attention, as it is a very tricky task. A 52-Set definitely makes for a very interesting learning curve!

Hi Bob.

In reply to your question on water transfer decal colours, it could easily be done that way, yes.

From what I can piece together, the original decals were printed with the layers of paint colours built up on them. This included the small patches of luminous paint. When you look at the original decals up close at an angle, you notice they are not completely flat on the radio panels. There is always a subtle rectangular raised patch visible, where the pad of luminous paint was applied. The lettering in this instance is the clear portions of the decal allowing the 'white' luminous paint patch to show through.

If one is restoring a panel and not worried about the decals being luminous anymore, white background transfer sheets are a good fit. If, however, one wants to preserve the glow in the dark appearance of the panel, things get a lot more complicated, quickly. Commercial printers could possible reproduce the original luminous decals, but at what cost? I have some ideas to work around that problem floating about in my head at the moment, but have not yet made complete sense of it all.

Adding to the problem, is the luminous paints used during the 1940's. They all have a very similar, if not in fact identical appearance in daylight: a milky white colour. Under UV stimulation, however, some glow blue, some yellow, some orange and some green. Probably other colours and shade factors out there as well. Blues and greens are reasonably common in craft supply places today, but I have not looked enough to see if other colours can be had with the required milky white daytime appearance. I have found an orange one, but it comes as a neon orange daytime colour. Yikes!

Dave, I would never have believed a loose 52 set carrier would be out there. Good find!!!!! I think you and I need to mix up a batch of matt brown wrinkle paint.

Actually, Bruce, it was part of a complete set out of Quebec. The Supply Unit and Sender are its mates. The complete set was $200.00 Cdn. I did not need the Receiver so gave it to Jacques Fortin to save a bit on shipping costs.

Its interesting, Bruce, in the roughly three years I have been looking for 52-Set parts, two complete sets have surfaced. This one and another about a year ago in Alberta. That one started out at $400 Cdn, jumped to $1,000 and then went dark. It might still be out there. Neither of the owners knew to identify what they had by the information on the ID tags on each component in front of them. The sets showed up on line as ‘Old Army Radio’, ‘Antique Military Radio’, or some other description. If you look on line under those types of terms, you get swamped with hits. Thousands of items pop up, covering all decades from WW2 to the present. Makes it really hard. I have come to suspect these sets, though few in numbers, are still very much out there. The trick is flushing them out.

It will be interesting to sort out a good wrinkle No. 2 Brown. Very few enamels still out there and even fewer wrinkle options. Compounding the problem is the fact ‘wrinkle’ does not seem to define a single thing, but more typically a spectrum of paints, all of which seem to show up on wartime wireless equipment sooner or later.

While I think of it, Bruce. The mounting hardware securing the Receiver, Supply Unit and Sender in this 52-Set was missing. My Remote Receiver Case has 1/4-20 hex bolts holding the Receiver in place. I am running with that for the Carriers No. 4 at the moment, but find it interesting there are no tools in the set Tool Box to accommodate hex bolts of any size. There are, however, three different sized slot head screw drivers. So, perhaps the mounting hardware was slotted, round head 1/4-20 machine screws. Access to all the screw heads would be a challenge for any of the three sized screw drivers in the tool box, as there are so many knobs, dials and fiddly bits sticking out on the front panels. How is your 52-set installed in the Carrier No. 4?
