A museum up in Scotland (a former RAF station) has recently had a deactivated ex-RAF Bofors 40mm gun donated to them. The gun itself needs quite a bit of TLC and ideally the museum would like to restore it to its glory days... they have one volunteer who is an ex RAF Regiment bofors gunner but he's getting on a bit and can't fully remember the maintenance procedures as he last used one back in the late 60's.
Does any old and bold RAF gunner or armourer have (or know of) any handbooks, AP's, or guides that might help them remember the stripping and maintenance?
I can find a US Navy 40mm antiaircraft gun manual online, but I'm not sure if it's the same weapon as the UK version.
40 MM Antiaircraft Gun - OP 820
Thanks for your help in advance.
