Hi Tom, I can give you my best guess so far based on the couple dozen Fiamm compressors i have good knowledge of.
My theory prior to this TomYang thread was the first digit stamping indicated year of manuafacture and the following letter indicated a time within that year, maybe a month, maybe a week. So i happen upon you folks and thru the few earlier Fiamm i have seen, my theory still looks valid and even more so with the 3 digit stamping.
So, the 111, to me, indicates 1961 with 11 indicating (maybe, let's not rush this) November. And 207 would be 1962 with 07 marking July. The later 2000 MC/0 picture with a 2F stamp would be 1972 with F marking something. We actually need more data. And from a later era like 1964-1970.
I would now plead for more photos of stampings on Fiamm compressors and trumpet bases!
You would think with a simple system like this that the numbers would not be definitive enough, but what i find is the life of a certain style compressor is not very long during the 1958 to 1978 time period. So a 1976 compressor and a 1966 compressor might have same stamping, but totally different compressor. At some point, according to me, the 3 digit was revised to 1 digit 1 alpha.......i think 1965-66.
Not a big priority, but a fun detail.
hope this helps
