Italian headstamp help please

[charley777]

Greetings to all...

I am seeking help with the headstamps of these four 65/17 mountain gun cases.
65x172R x76.
Especially the dates of manufacture. Assuming that the single digit over the 3 digits has something to do with dates...

Shown with a 65x167R x75 French Mle1906 mountain gun round for comparison.
Thanks very much. last photo came out of order.....

The 3-digit numbers are the years (=Italian style of writing years). The french 65 mm shells were sometimes also fired from the italian mountain guns.

Thanks Alpini
So the first example does not have the 3 digits under a line and single digit ... is it WW1 perhaps? (1918 ?)


Wow sounds slightly risky ... that would eliminate the French case's bottleneck.

They were used in italian cases. Fired shells then have left hand rifling.

Yes the first case is made in 1918 by SMI.
