AirNGasman,
I must respectfully disagree with you about the aluminum "shells."
I have 2 that I purchased straight from Davis Schwesinger( one is serial number 001, new in box never used), and Davis made the brass shot shells himself. I know for a fact that mine( both) came with 12 BRASS shot shells, a 10oz Co2 cylinder, a wad cutting tool.
I have a spare stock that I bought from Davis, and I have the most valuable one-the first one made 001.
I may consider selling it in about 5 years for $2-$3,000.
It's one of a kind.
Every single part was individually numbered because each one was hand made and no 2 were exactly the same, so the parts had to be numbered .
