Info needed: cmp 13 gun tractor

[Richard Salter]

I posted earlier photos of my cmp 13 in which I was asking info about. Well I thought I would put a few pictures up to show progress of stripping it down, so far wiring harness removed and tagged doors off cab mounts off and the rear panel was only clamped in by the original canvas clamps from the body. The rear panel turns out its the roof from the back. All so if you look the original under coat and the original green paint
I would like it if any one can supply me plans to fabricate the rear body please.
