manicmike, I'm slowing going through what I have, and until I get into the new building, it's slow going! I plan on going through my puzzle box stuff this weekend. I wanted to have 3-4 complete boxes - and some day I'll nab a really early one (got outbid at $110 on the last one).
I'm not sure how many I have now, however I've got lots and lots of puzzle pieces that came with other stuff. I've got two people I'm sending parts too, and hopefully there will be a few more with puzzle boxes they need a few missing pieces for. Though I know I do not have extra screwdrivers. The number one missing pieces from any set of attachments are the screwdrivers and stilleto.
Some day - I'll have given away the "extras" and be down to what I want to keep. I never intended to end up with parts I didn't want, unfortunately way too often, the one part I do what shows up in a pile of common parts I already have an overabundance of.
