What was the significance of nickel plated shells? These two NPE shells are both 12A, but the brass one is 2 9/16" and marked West Meriden, while the nickel plated shell is 3", and the headstamp has the diamond surrounding the primer, and is marked Meriden Ct.
My understanding, whether correct or not, is these were all made by UMC, in Bridgeport.
