WW2 Aircraft Parts – Prefix Codes

 

When I first started for WW2 relics, many many years ago, I always concentrated on RAF and USAAF bases. My first love was always WW2 aircraft so this seemed natural to me. It was only in later years that I branched out to army bases, POW camps and other military sites. Very glad I did, but I’ll always love aircraft more than anything else!

Anyway, digging aircraft parts is all well and good, but how do you tell one piece of aluminium alloy from another? What on earth do all these codes mean on this Bakelite light switch? Why has this bit of metal got numbers stamped all over it? Why is there a circle stamped in this piece with some random letters stamped inside it?

Just a few of the questions that went through my mind when I first started. Understanding these codes and stamps is half the battle when trying to identify aircraft parts. You have Air Ministry reference numbers; aircraft ‘part’ part numbers; prefixes; suffices; half codes; full codes……it can be quite mind boggling.

So, to help identify those parts, I’ve rattled together this page with all my part number and stamped number references on it, along with a few examples of things I’ve dug in the past. I hope you find it useful in identifying that aircraft part you have!

Air Ministry codes to begin with, then aircraft part codes…..

 

AIR MINISTRY PREFIX CODES

The manual containing all the code references does still exist, but when I spoke to RAF Hendon who have a copy, they explained it was 26 volumes long and wasn’t digitised! So, the prefix numbers giving an item ‘group’ will have to suffice!
