Wire-3 Fitted For Wireless Box details

Here is the other mystery bracket.

Some more photos of the basic layout.

Another mystery is figuring out what the seat bases looked like. As you can see in the these two pictures the seats were mounted to the floor using three bolts. However these mounting points are outside of the normal CMP seat base. The manufactures part number is B340056

There were two battery trays on the truck with the following manufactures description and part numbers.

Stand Batteries Assy, RH #C38272
Stand Batteries Assy, LH #C38273

As you can see there is a couple mounting holes on the floor. Highlighted via the red arrows. On the left side is a larger oval hole. This was for the power cable from the Chorehorse to come up to the C5 charging board. It is highlighted with the green arrow.

Here is a shot showing the power cable in the conduit. The relative position of it would suggest it is coming up via the oval hole and then connecting to the C5 charging board.

In the second picture you can just make out the battery clamp posts with wing nuts. There is two posts visible under the tables pull out drawer and then just a single one visible to the right of the table.

Jordan a C15TA uses three mounting points similar to your box. The big difference would be the foot wells on the TA making it easier to sit. The mounting tabs are welded to the seat and you will notice the rear one isn't in the center because of the hold down strap. Not sure this helps but it's an idea.
cheers,
Barry

Hmmm...

Are the 3-hole seat mountings the tubular variety as used in the Wire-5 truck? (See other thread in the Restoration forum.)

The tray under the table may well be intended for 4 x 6V 85AH batteries since the aerial base 'cage' on the roof is for Aerial Base No.1 which was used with Wireless Set No.11 and that used 4 x 6V 85AH batteries for the vehicle fit. The tray may have been left in place when a WS19 was fitted.

I think the long bolt sticking out of the RHS of the table frame is definitely a mounting for a drum of telephone cable. The rectangular plate probably goes against the table frame to space the drum away from the flat bar (and any irregularity of the weld) and keep any rolled edge of the drum from fouling it. What is the spindle diameter and available length of the bar? It might take Reel, Cable, No.2 as used with the early control units, or the rather later split drum (Reel, Cable, No.4?) used with assault cable No.2 and later with D10. (It's also possibly a much later addition to the table.)

I don't think so. I just looked at the tube mount used to raise the seats in the Wire-5 box. They use 4 bolts in a pattern approximately 4" (wide) x 11" (front-back of seat) for mounting to the floor.

A big thank you goes out to another MLU'er for unearthing the following original documents dealing with the Wire-3. These were a packing slip/inventory of one of the boxes being shipped from Brantford Coach and Body.

It is believed that most of these part numbers were Brantford Coach and Body numbers and hence don't match up to any GM #'s

Obviously I would love to positively identify all of these parts. Some in particular are the seat mounting brackets and the type of hurricane lamp and its mounting bracket.

There were also two sheets on the tools shipped with the truck.

Barry, thanks for the info on how the seats were mounted in the C15Ta. Im not sure this is how the Wire-3 had them though. When I tried out my seats in the box the other night, they seemed to match up to the wheel well height pretty closely while mounted on the original seat sliders. I have been told the seat mounts appeared similar to the 8cwt wireless truck seat mounts.

Chris, your point about the tray under the table possibly being for another wireless set is very good. The table tops have a variety of different mounting holes and I believe it was intended that this truck could carry the WS9, WS11 and WS19 radios.


I tried out the two cable reels I have and they both fit perfectly on the threaded rod. The rod is 1/2" diameter carriage bolt. Im not sure if this was added by the end user or came from the factory. You can see that the smaller diameter reel does slid around on the rod. If this was in fact what it was for, Im wondering if a compression spring was on the rod between the mounting bar and the square plate. This would keep it away from hitting the bar.
