Must be the Canadian Club?
What is there about that lovely country that makes men pickenickety? Man after mine own heart!
The difference in brake drums traces back to the pre-war period when the requirements for a military chassis that complied with War Office Spec.36A (to E) were being discussed, and it was established that for 16" wheels there was a limit to brake drum size that could be used in connection therewith. What you say makes sense to me having read the hundreds of pages in the files, but may not be obvious otherwise.
The Ford chassis had technically a 1/4" longer wheelbase than the Chevrolet. However I have just noticed that there was a diifference in Chevrolet/GMC chassis wheelbase in the civilian/MCP line: there was a 158 1/4" chassis in the COE 2-ton range, which would have been similar to that of the Chevrolet C60L in theory. The '160"' wheelbase chassis were actually 159 3/4" strictly. How on earth did they quantify that? Ford's clearly thought that their 1/2" made all the difference...oh no I'm going done the same path!
Can anyone confirm the wheel size please on the 2-pounder Portee?
