Slow6....
These are the some of the rarest, and most sort after planes in the tool collecting world, because they are the first efforts of Leonard Bailey about 1855, well before his connection with Stanley R & L co. There are many collectors out there wanting to get them.
....you have the 2 and seven back to front:)...$7200.00 will be closer. My guess is it will go above 5000 and might get close to 10,000. That one is in the best condition I've ever seen. There might be 2 or more blokes at the last second that put "unbeatable" bids on it... Given the downturn in the US economy it might loose a few bidders, however if it goes over 10...I won't be all that surprised!

Peter.
BTW, I like the treatment you gave that Stanley plane with the Walnut handle!
