Chevrolet coolant condensor can

I see 6 digit numbers prefixed like that all the time for early the US military items, prior to them adopting the FSN, and later developing that into the NSN. Perhaps it is a US military number.

Otters mid way through production were fitted with the standard CMP can. Early Otters didn’t but a modification kit was released to fit the cans in them.

I agree with Rob, I think that is an American part number. The 'C' refers to the size of the drawing of the part, 'A' being the biggest. It does not indicate a manufacturer or a revision.

Thanks to Rob and David - I went and dug out some of the stash of blueprints I received from Alex Blair's collection to look at their numbering. One drawing in particular caught my eye...
Drawing number C-321587 originally issued on paper marked as the Army Engineering Design Branch, crossed out and stamped as the Directorate Of Vehicle Development, Q.M. G. Branch, Dept. of National Defence has a reference to GM part 5820086 and depicts a "Flange-Transmission-Drive-Shaft". This drawing is dated 5-2-47.
Definite proof that the format of "C-######" was used to number drawings within the AEDB and QMG Branch, including automotive parts.

A very quick check in several CMP and GM armoured vehicle manuals didn't find 5820086. Hopefully someone else will have better luck finding the application of GM part 5820086...

to me it looks like a T 16 Carrier condenser can , maybe somebody can check a T16 out.

[Maurice Donckers]

I just checked it , and for sure it is T16

Based on the drawing, it is actually not to difficult to recreate a condenser can with simple tools and small adjustments to the design
