Breda, or is it?

[Joolz]

This one had me scratching my head:

The cases are Breda .50/12.7 x 81SR, but what about the projectiles?

The top one has a case marked BPD 40 S, so I guess Bomprini Parodi Delfino. but the projectile has no markings on it whatsoever (and what looks like a red repaint?).

The lower one really has me puzzled. The case is marked SMI 940, so Societas Metallurgica Italiana. But the projectile seems German marked. Around the waist is: eet 13i 42 (170 within an eagle). Around the fuse it has: 1532 azg 41 (61 within an eagle) 206.



Is this a 'frankenbullet' and if so, what would the projectile be from originally?

Thanks again,

Joolz

Also, I'm pretty sure I've worked this one out, it's another Breda, but the 'big brother' to the ones above - a 20mm x 138 B - made again by BPD.

Your German projectile most likely came from a 13x64mm Belted round for the MG131 aircraft machine gun. The correct cases are fairly common so it should be easy to find a correct case to put it into.

Your 20mm round was used in the Italian Breda and Scotti 20mm anti-aircraft guns.
