I picked this up the other day,looks to have been cutdown as the top has been folded over to the inside to form a lip.
It measures 15cm tall,base diameter measures 6.3cm and 5.5cm across the mouth.
I’m guessing that it’s an early case as I can make out 97 stamped on the base,which I presume to mean 1897.
Also,it has a type of primer that I haven’t seen before where the tube screws into the base of the shell.
Is this a shell that has been cut down to form a blank round,or has someone messed around with it,trying to make a vase or some other kind of trench art?
Also If anyone could identify the case I’d be extremely grateful!
