Unknown manufacturer on Belgian 75x277 case for Krupp gun

[Hoeksel]

For these cases I know FN and FZ, both being Fabrique Nationale in Herstal (FN) and Zeebrugge (FZ). Does anybody know the manufacturer OM?

Hi Hoeksel,

for OM, the only result I have is "Olin Mathieson Chemical Corps, Bridgeport, Connecticut, USA" !
But I don't think it's the good one for this case !

According a Belgian collector this would be Mecar S.A. (Belgium), founded in 1938.

On a 2nd case I found a logo, that actually looks Swedish to me. The case is intended for the Belgium used Bofors 7,5 cm M34 fieldgun. Anybody recognizes the logo?
