What is the case length of your cartridge. The tic marks on the base are one characteristic of pinfire cartridges made by Ethan Allen. While these usually have 4 tic marks, according to Suydam’s US Cartridges and their handguns, they sometimes have three. Allen as well as CD Leet produced 12mm pinfires under Christian Sharp’s patent # 34897 between 1862 and 1870. If the case is around .767" long, it is probably an Allen made cartridge with those tic marks. The Leet and Allen cartridge cases were in between the European short and long cases, which makes then somewhat unique.[/quote]
It is right about that length.
I have another that is just a hair longer that is also no headstamp but is still shoter than the longer ones.
