Looking for M38A1 info

[BCA]

Convoy light and switch: I have the Modification Instructions for installing the convoy light on 3/4-ton Dodge (7 Oct. 1953) and 2-1/2-ton GMC (30 April 1953). Both imply that later production vehicles already had the convoy light installed at time of production and that the modification was to add it to early vehicles. In the case of the Dodge the early vehicles were pre s.n. 91401714 (3/1953).
The implication is that by March 1953 the convoy light was factory installed on Dodges and GMC's. I do not have the Modification Instruction to deal with the M38 and M38A1 jeeps. But it follows that in 1953 the convoy light was to be added to the M38 and M38A1. On M38's they always appear to be a locally added feature based on the location variation and crudeness of the dashboard hole for the switch. I haven't paid much attention to convoy switches on the M38A1 CDN (1953 production).
So for Dale's April 1954 American M38A1 that was brought into the Canadian inventory it stands to reason that it would have had the convoy light added as part of routine local E.M.E. instructions. When or if this happened is to be determined. Finally, it was produced 4/53 but when did it arrive in Canadian inventory? Unlikely in time to be a Korean veteran.
