CMP trailer

[Snowtractor]

The tires are aircraft tires that say they are 32 x 8.8 14ply tubeless, though they have tubes.

cable system for the rear parking brake.

A look at the hitch and empty area where the hydraulic pump would go.

[Snowtractor]

The lunette ring is bolted to this hunk of cast metal and slides back and forth as pulling and pushing of the trailer applies. The crossbar that the hitch is in contact with ,and also attached to with the spring , increases either force or travel (I would have to measure the length of the levers welded to the crossbar ) to push on the hydraulic pump. The spring just keeps the crossbar tight to the end of the lunette ring shaft. And the pump is gone.

note the solid turn table and the grease nipple for the deck by the data plates. Also I don't know what the ET18 means on the front. The PFRA that owned the trailer has had it since the 60's and the guys said they never had a marking system like it.

and a rear view. The hitch was welded on afterwards.

Has anyone seen this type of trailer marker before ? it had reflectors in the holes in the raised "T".

Sean, looks like great buy! Vehicle code 4M-F-GS, yes, this is a very nice example of the Trailer, 4-wh, 2-ton, GS.
"All" you need to do is fabricate a GS body, of which Mike Calnan has an example so he can provide dimensions.
The maintenance manual / parts list you need to get hold of is SB-13. I would not be surprised the hydraulic pump is a standard Ford master brake cylinder (my 20-cwt trailer has Ford mechanicals throughout).

The love for trailers is a family thing, eh?

Once again that book comes to the rescue. Interesting that the box is all metal, makes it a bit more of a challenge. In the serial number 21-4M-F-GS-2-1 I wonder what the 21 and the -2-1 stand for. Also ,I see in the book that the 20-cwt, GS has "impact brakes" also and the hitch setup to mount the hardware looks almost identical to mine. If you are out and about with a Camera, Hanno, how about a picture or two of the master cylinder for the archives. Maybe a serial number too.
As for the wagon master, he is just biding his time ntil he can get to the keys for something.

Sean, how about a view from below taken from the manual SB-4A? Looks like the same set-up to me.
Finding someone with the AEDB design records might help too, that's how I found out about the Ford brake parts on my 20-cwt trailer.
A serial number I have not found (yet).

Great picture Hanno, thanks.
I have everything in the photo master cyclinder mount plate etc., except the master brake cylinder, even the hydraulic line and fitting is sitting there.
I am not sure I know who Mike Calnan is. His GS wagon is complete? And located where?
ANy heads up on the SB-13 manual ?
Sean

PS: Hows the littlest one doing Hanno?

Sean, the master brake cylinder is a standard Ford item, still available new today (bought one myself last summer).

Mike Calnan = Gunner, see his postings in this thread above.

PS: The wee one is doing great, keeping us up at night every now and then, but otherwise very sweet. Not sure if she´d pay attention to Shamus in his cool ride already, but I guess that won´t be long :

AND.... where did you get it and how did you order it without a serial number?

LOL, sure do change fast, Shamus is facinated by other babies now and I finished putting red highlights on the wheels and LED flashing lights on the rear now on his "pimped up " ride

Hi Guys:
If the price is right, snap that Sask wild flower up. These trailers are not often seen and its worth saving. The GS bodies were pretty simple and I have an example so can provide dimensions. Even easier would be the flat deck version with posts and chains (see Gregg's book for a photo as I still am not computer competent enough to post 'em).

Good luck whoever goes for it. Let me know and we can compare notes!

Cheers! Mike

Hi Mike,
having finished my preemployment welding course on friday , with a 95% average I might add , I am ready to start to tackle the steel body of my GS trailer. A wood deck was put on mine so I need some decent measurements to start the reproduction. Any chance of getting some dimensions and pics when the snow melts?
cheers

Hi Sean:

My trailer is the rusted heap in Bob carriere's photos above, but, I do have an original box mounted, in all places, on the back of my IHC halftrack. I bought the halftrack from the late (and Great) Bill Gregg and he told me that it was an army workshop mod to make a fitter vehicle for transporting and swapping tank engines. makes sense as the 1/2 tk also has the fittings for a gin pole on the front winch mount.

Anyway, the trailer box is well fitted onto the back of the 1/2 tk and will be easy to measure when I can get at things in warmer weather (its buried inside the barn three rows back in the "some day I'll have time to restore it" line-up!

I will probably have it copied here in Ottawa by a truck body mfr when I do the trailer up. Nothing too complicated- all flat panels and easily bent reinforcements. The tailgate might be the most complex part as it has foot holes in it! I could likely weld one up myself but on 5 Feb Her Majesty is shipping me out yet again and I will be away until the end of May. I'll still be on net so I'll continue posting.

Hope you don't mind waiting that long.

Cheers! Mike

Hi Mike,
that Queen of yours certainly keeps you hopping!
As for measurements, they can certainly wait , just knowing they still exist somewhere makes for muc easier breathing. Let me know if you need anything from this end.
thx

I bought it off a parts dealer at a military vehicle show. The current part no. is for the master cylinder is EIS EH572.

Hope the trailer is being restored one day, can´t think of a restored one anywhere in the world.

Cheers,
Hanno

(P.S. great eh? getting a response three years after asking a question)

Since Hanno has gone to the trouble of resurrecting a long dead thread, I thought I might as well show some photos of a similar trailer I picked up at the local auction last summer. Unfortunately someone had recently swiped the data plate from it. It is sporting some 16.5" california winter tires (no tread) on the original cmp rims which I guess is one way of dealing with the larger rim diameters.

I needed another trailer like I needed a hole in the head. But the disease we suffer from does not let us pass up any CMP. So it will wait for a cargo body to appear.

I have seen a number of the trailer cargo bodies around Saskatchewan, in fact I think I even had one myself for a time, but ended up leaving it at a scrapyard a number of years back during a yard cleanup.

[Gunner]

Hanno/Rob:

Thanks for bringing this back to the front! I had forgotten that I promised Sean the box dimensions and he was obviously too much of a Gent to remind me

I'll put it back on the things to do list for this summer when I get back from Africa, again!

Sean: we should get this done about the time that Shamus asks for the truck keys!

I normally don't do the list of "my stuff" but I wanted to have some fun and show that I like trailers! Artillery pieces (which some misinformed bin-rats think are just funny trailers!) even more!!

Politically correct notice: I respect bin-rats and count many highly professional bin-rats as close and dear friends... doesn't stop me from calling them bin-rats!
