Looking for info on 3A1 MGO body

[Max Hedges]

I am looking for photos or drawings of a 10 foot all steel no 3A1 MGO body as we are looking to make one up for our C30 cab 11 any help would be appreciated.

Does anyone out there have one of these body types

Max, I looked through my factory photos CD and 1941 illustrated body parts list and came up with the following. It seems there's a typo in the model # for the 30 cwt general service body. It should read (3A1).

The parts list says the first type had hinged sides and the second type had fixed sides so I guess this is the first type.


The front end.

Here's the GS type superstructure. You didn't say which type you were interested in.

parts list side view.


parts list rear. Max, on one of your posts on your other cab 11 thread you asked about the chicken handle. All of my 11 cabs have them.

I found some more on the factory photos CD.

Side view.


Rear end tarped up.

This one has one of those discussed three tone camo jobs.


I'm not sure what they're trying to do in these next two pix.

Here's the page from Greggs Canada's Fighting Vehicles 1943-45.


And one from Greggs Blueprint for Victory.

Think this may be the Australian version of the frame.

If you have a winch you could always come up with the derrick version. The box is the same as on the GS versions. The super structure pix I posted is for the Canadian GS body.


This is the general service body. The one type of superstructure is for the GS variants and the other type is for the derrick types.

A side view without the tarps. These pix should help quite a bit there Max. I'll scan the parts lists and post them in the next day or two.

Max,

I hope these help....

This must be the second body David is referring to, no hinges on the sides (?)

The next 8 posts are the parts list pages.

That parts list manual from Alex Blair is a valuable resource for anyone with 11 or 12 cabs.

The breakdown body on these pages is different from the rest. I don't know why they put it in with the rest of them.

[cletrac (RIP)]

In the manual they also list a wooden version but no pics.

Almost done.

Last one. Now about all you'll need are some measurements.

[Max Hedges]

I have some mates that own a workshop and are restoring a GMC and they are willing to help
Would it be alright if I copy the pictures on to a disc as they would like them in the work shop while the work is being done
also some measurements of the body would be good,as they said once they had a couple of measuremenys they would be able to work others out from the photos
and any idea what thicknes the floor plate is
You blokes are a great help

I wish you well with that project . But believe me , it isn't a weekend job .. it will take over a year .. or more . I built a 1A2 body from scratch for the C8 . Without the engineers blueprints (which I didn't have), some guesswork is needed here and there. Photos are great , but they won't give you that final ' detail ' that you want . It's not a cheap undertaking , and it's painfull if it turns out looking like a non-original copy.

You need access to heavy tools for cutting , folding heavy gauge steel. The panels on that body look to be fairly long , may be difficult finding a guillotine that will cut that length.

I don't want to put you off , but the project will have your hair will turn greyer .. if that's possible

Max, the floor and other panels will likely be the same gauge on most types of body. Note that the floor sheets fold up about an inch along the sides. This was pretty common on the various bodies too. Around here it's easy to find a shop with a 20 foot wide metal shear and break. On a lot of the bodies the floor panel is two pieces joined down the centre but in the pix it looks like this one is one piece.
I came up with these dimensions with my AutoSketch program. The only measurement I had was the 201 inch length so I cropped the pic at the front bumper and rear of box then did measurements on my work page until I had 201". Next I inserted the picture inside those measurement lines and presto! Now with the dimension tool I could just click on any two points and it puts in the measurements. Kind of neat! I'll do the front and rear views too. In the real world the measurements would be in 1/4 or 1/2 inch multiples instead of decimals like I ended up with.

Excellent job mate but I would be a little wary of the length measurements as the photo is not true square on so this will vary a bit. Vertical height measurements should be pretty right though.

[cletrac (RIP)]

Cliff, it's close enough to being straight on that the differences will be minimal. Here's one more.
