headstamp

I acquired this beauty at a second hand store, neat story read on..... I'm a treasure Hunter like to the thrift store environment and upon discovering a new treasure trove I hurried through the door. Immediately the shop owners mother and I struck up friendly conversation as I shopped around...

I found this shell casing in an area that had items dating from the 1850's forward. Thought nothing of it until I tried to decipher the headstamp when I got it home. Some kind of alien code?? :laughing7: Included regular .45 casing to contrast.
