Many, many, many moons ago I traded (with a board member through another board member) a 1911 Weaver in OK shape for a 'cut' 1909 Gandil...and would probably do it again today if I had to. The 09 Gandil is much tougher than the 11 Weaver even though the Weaver has been valued at more in recent years, I would assume because of demand...certainly not because of supply.
To be fair, it helped that I had 2 Weavers at the time also
