Hey Pettifogger, I put mine up on Gunbroker. Nowhere I looked showed the innards of this tool, so I'm putting my ad up here, NOT to sell the thing but to contribute to the information we got here with a lot of pictures.
http://www.gunbroker.com/Auction/ViewItem.asp?Item=145141278No post that I could find showed the inside of the tool, and every one was missing the decapping pin, which I think could be replaced with a framing nail with the tip ground off.
Thanks for helping me sell this for my buddy.
