I have a 40mm Bofors round that has no colouring on the projectile. It looks like any paint has been scoured off in the past. There is evidence in the lettering and the flats of the plug that it has been painted with a dark colour in the past.
Because the fuse area is marked ‘FIRING PLUG’, my suspicion is that its a projectile that has been converted for practice use?
Round is inert. No markings on the case body, but lots of info on the projectile itself. Hopefully the pictures will show those that I cant describe easily, but here is what I can read on it -
very top of fuse/plug - L.G. BR 9 51
over stamped on rest of fuse/plug - FIRING PLUG REP 251 255 MK N2
Original stamp on fuse/plug - 255-1 LG 4 B K
various lot numbers on the projectile body, all jumbled, DMC LOT 9 '44 is readable
What I would like to know is what the correct colouring should be, as it is my intention to repaint the projectile for display. (just noticed that the camera seems to have picked a bit of colour up in the lettering which looks royal blue?)
