13Pr case

[Krt7.92]

Hello,

I've got this 13Pr case without the "13Pr" marking. Is this common?

Not common in Australia. I have a Mk11 dated 9/16.
Bethlehem Steel Co, USA contract 13Pr 6Cwt Artillery gun.
Your headstamp is too hard to read but I have not seen a Mk1 case by BSC.

It's dated 11/16, primer is also 1916 dated. All 13Pr cases i've seen so far are stamped 13Pr (+ Mk), but this one is not marked as such.
