Among the items or aeronautica acquired by my father (LAC/Skyways up to 1958) I have a compressor with an AM serial 37G/50 and a crudely punched number 67372. Also R490 and A10 G7F within circles. I suspect it came off a Merlin because it looks exactly like the one shown on p69 Haynes Supermarine Spitfire OWM. Can anyone please tell me what significance have the numbers? does /50 = 1950??.

Compressor pictures
Thank you for that information. Now, I think my father intended to make a tyre pump with it. Do I – or shall I mount it on a block of mahogany and give it to my wife? Rhetorical question.

One of our Heywood compressors is stamped 37G/501 and the serial number is very close to yours.
They were fitted to Merlins and other types, I don`t know which engines didn`t use them
They were also manufactured in the USA by a sub-contractor to Packard, then the AM ref is 137G. One here is stamped 137G/3. I always assumed these were originally only fitted to Packard Merlins but I don`t know.
Anyway, it is a general services compressor, whereas the Godfrey is a cabin pressure blower.

My 1949 edition of AP1086, Book 1 Vocabulary Of Sections shows a broader range of content within Section 37G than those listed by aircraft clocks.
37G/50 is the Section Ref.,btw, not its date.
I suggest you upload a few photos of the compressor: someone will be able to identify it for you.

Section 37G
Section 37G is the section for the following:
Godfrey cabin superchargers, Godfrey air compressor SRM 210 Mk 1, Godfrey air compressor SRM 215 Mk 1
You would need to look in this section of the AP1086 to found out what the reference number 50 is exactly.
