Jeff, yes and no to your question is the -1 variation worth the price you saw at the FT Worth show. Yes from the standpoint of scarcity. Only 35 or so have been documented in the last 15-20 years collectors like myself have been chasing after them. It wasn't until the internet got going in a serious way that most of the 35 were discovered. As the owner at one time or another of a good 1/3+ of those we know about I can say they do show up now and then but rarely enough that if a Model 29 collector wants to fill the -1 hole in their collection of pre-29 to -10, my advice is to buy it when you find it. You might very well not get a second chance unless you luck on to one where the seller doesn't know the significance of the model number. The seller in Ft Worth obviously knows what he has. No for the reason that if you're patient enough you might be lucky and find one for considerably less$. But again, with only 35+- showing up after the past 20 years and with a full blown internet, almost daily gun auctions somewhere, and the -1 mystique only getting bigger, like any other model, it's worth what someone is willing to pay for it. Good luck!
