There was at least one run of the original Navy cans that were made by KAC for HK. This is the one pictured and described in my post earlier in this thread. I included pics as well . The second run, which yours is from, was done years later. That run was done due to collector and shooter demand as the originals became quite rare and expensive.
The markings on the second run are different from the original. The originals were HK marked as you can see on mine.
The cans are different as well.
