I have a 30mm aden projectile stamped BJB-57 does anyone know what the BJB stands for.
also a 20mm oerlikon stamped MK3-HXP-21-83 does anyone know what this projectile is and what colour should it be .
Thanks

BJB is Bayliss, Jones and Bayliss of Wolverhampton. They also made armaments in WW2.

HXP is the Greek Powder and Cartridge Co., Athens, also known as Pouderies et Cartouches Hellene.

It looks like a ball projectile so black is probably correct.
