I cannot see another marks other than the *v previously mentioned. It still shows the "lion over the PV" of the 1924 nitro proofing.
So when do you think it was made.
And in reguards to this cartridge.. Is this a nitro for black round or black or just early smokeless? Any idea where to start the loads? Any data avaible some where?
Once again thank you for your efforts.
