Yes a Scammell has a certain presence.
The Ford and Chevrolet CMPs, are not quite as interchangeable as with the jeeps, but there are still plenty of shared things, and the Ford parts book even list the Chevrolet axles as some where built with these. I had a F15A (hidding between the Scammell and Chevy) with a Ford front axle and Chevy rear. The Chevy was considered to be the superior in terms of reliability, so much so certain units specified that they wanted only Ford with Chevy axles.
The chassis on the picture is of a Gun tractor, so it has the F60 size parts (Heavy axles, 20" wheels etc), but is only a 101" wb (like the 8cwt and 15cwt) and where the F60S was a 134" wb.
And yes correct, its the first type, cab 11, a design which where lacking in accessibility for maintenance and creature comforts.
I suspect the reason for not producing CMP´s (Canadian Military Pattern) to the civilian market, is that they where deemed too rugged for commercial sales, further more there where so many available surplus from the armies I think it would have been hard to compete.
But in general, I can more or less only think of a few military vehicles types that was sold commercially after the war, and all of these where basically civilian prewar vehicles that where adapted to military service.
maybe the general public where tried from war and wanted a fresh start.
