At a flea market this weekend I picked up a working carcass for a Stanley 113 as described in Patrick's Blood and Gore.
The seller said it was broken and good only for parts but it only has one removable part, which looks like the frog. That part's broken which is probably why he thought the whole plane was. The sole-bending mechanism works fine. Except for that one part there's nothing broken, cracked, or stripped.
So I've either got a conversation piece or the start of a restoration project. I'd prefer the latter but I'm fine with the former.
I'm still googling and coming up with possiblities, but does anybody have any suggestions about who I should be checking with? Charlie?
