What research has lead you to believe it was made in Baltimore?
Here's an example of 1962 Chevrolet US serial numbers;
2C365B100001
2 = year (1962)
C = Conventional Cab with gas engine
36 = Series (3/4 ton)
5 = Body type (Panel)
B = Baltimore
100001 = Unit number starting with 100001 at each plant.
Your model designation would be C3605S here in the US.
C = Conventional Cab with gas engine
36 = GVW classification (3/4 ton)
05 = Body (Panel)
S = 30 Series ordered with optional 7800 pound GVW
I can't help with the engine number other than to say it's not a US format.
