They look pretty nifty. You may or may not want to make some new snazzy wooden bars to up the price a bit, but they would probably sell best on ebay or another site where folks can bid for them.
I've seen old tools, especially older woodworking tools go for a pretty penny on ebay depending on how you word your advertising. In fact, you could probably ask folks here to help write your ad to see what suggestions come up.
Heck, I'd probably get in a drunken bidding war for them myself if I was still a drinker..
I figured it's time to change my signature so hold your breath. This is it.
