Need ID

Can someone help me ID this case, around 75 cal. but case mouth is a bit deformed. Necked brass, rebated rim, berdan prime.
Projectile was around - .735
Would like to see a picture of a loaded round. Thanks; Jack

20mm Becker?

Orange you are correct, it is a type 2.

Jack, can we get a bigger image of the head stamp?

I’ve been trying to enlarge the image on photobucket but can’t seem to do it.

Jack, once it is on Photobucket you can not enlarge it anymore. You just need a higher resolution.

I think this will be a bigger photo.

Great! Interesting head stamp!

The case maker then is Basse & Selve? JG
