Came across this case.
75mmx230
Brass case and iron base.

Headstamp :
12 O`clock : square in a circle
3 O` clock : 16
6 O` clock : Sp61
9 O` clock : 351

Can anyone identify this case?
Is it a common case with a iron base?

Thanks in advance.

It's not a 75 mm, it's a german 7,7 cm case. Look at the typical double crimping on the collar.

Yodamaster ist right...

the factory is Rheinmetall and yes, they are common with steel base.
