I've seen the roller version on the Brake Grinding and Press trailer, not sure about other uses. Also looks likely to have been plain impact brakes rather than boosted. ANd the towing eye has been replaced with a later version so likely the master cylinder from the brake system may also be removed.

I'm pretty sure this is the "Heavy Compressor Trailer"

I have 2 of these trailer chassis at home, and they are the GS trailer. That is, unless someone sees something about this one that I am not seeing.

The base sitting atop of the trailer is the stand for the M46 or M47 twin 50cal mount. The shield shows up in another photo for the 25pdr chassis. The nutbar from Shilo bought that as well.

Guess I'm making a roadtrip come Victoria day weekend in May.

i reason that the taper to the frame doubeling at the back is shown both in the picture of the trailer and reflected in the line drawing on page 180.
the line drawing for the GS trailer shows no such taper on page 171

I have volume 7 of the design branch records here, and in the chassis section it shows the doubling on both the 4 ton and the 5 ton 4 wheel trailer. The photo of the 3 ton trailer is not definitive as it is more of a front 3/4 view. I think the doubling of the frame towards the back is to simply bring the level of that portion of the frame to the same as the front turntable, so that the spring brackets can mount in such a way that the trailer sits level.

I have seen the same doubling on the two 4 wheel trailers that I have at home. Both of them are "impact type" brakes.

Edited to add: I just checked an original copy of "the vehicle data book" and it also shows the doubling of the frame on the 3 ton trailers.

Also, according to the design records, the 2 ton trailers were not on Cdn contract. We stuck to the 3 ton trailer, while the 2 ton (10 ft box) and the 5 ton were done to ministry of supply orders.

its the taper on the front of the doubled portion that made me go with the compressor version. maybe there will be tags on the trailer. another note i see the GS is dominion trailer, the machinery are Chrysler and the compressor says various because i was curious as to the fruehaf reference.

Agreed that the Design Record refers to the 2 ton 4 wheel GS trailer as being to S/MECH. 6409 however there is what appears to be an example of this type (with the body extended to 12 foot length by cutting off the headboard, splicing in extra side and floor material and re-attaching the headboard) in the vicinity of Ottawa. It was collected in Eastern Ontario - hard to understand why an orphan would have been brought back, so I will guess it probably never went overseas. I don't know if this is relevant but it seems to have been painted a very similar yellow to my ex-RCAF radar train C60L (with winch). It also came from the same general area so there might be some form of connection.... Perhaps once I get the 15cwt trailer done, I will try to convince the owner to sell me the 2 ton and start on that....
The same collection has a Brake Drum Grinding trailer that unfortunately was cleaned off just above deck level. (I think it was sourced in the vicinity of Huntsville.)

After checking the parts/maintenance books for the 4 wheel trailers, both/all have the stacked frame arrangement at the rear, however, I need to clarify my guess of the identity of Dennis' trailer frame. Based on the fifth wheel appearing to be of the ring and roller variety and the statements in SB-13 that the ring and roller fifth wheel was used on the "60 Ton Press" and "Brake Drum and Surface Grinder" and plain plate fifth wheel was used on "GS" and "QMG-MT" trailers it appears Dennis' frame is probably from either of the "60 Ton Press" or "Brake Drum and Surface Grinder" trailers. This is partly borne out by the lack of rear auxiliary springs and air power system for the brakes that are listed for the QMG-MT trailer.

Like many things CMP, the trailers had common parts made by a variety of makers to similar or standard designs. Like the trucks, brakes were Ford (including master cylinder)(except air components by Bendix-Westinghouse), springs were lifted from CMP trucks (Ford on 15 and 20 cwt 2 wheel, Chevrolet for the 4 wheel trailers. Frames by several makers including Cusson Brothers in Montreal (Fruehauf as an existing trailer maker would be another likely source.). The ring and roller fifth wheel assembly is listed as being a Fruehauf assembly (might have been used on frames by other makers), perhaps that is the origin of the description in the ad?? My impression is that Chrysler did a lot of the assembly of machinery equipment into trucks and trailers that others had built. As an example, most of the manuals for machinery components of trucks and trailers are published by Chrysler but the machinery bodies were typically either Lindsay or GS pattern mounted on Ford, Chevrolet or Diamond T chassis with lathes, drills, saws, generators, welders, chargers and presses etc from standard commercial sources mounted into the body by Chrysler.
