Yeah. Seems they are rather rare, and that collectors (rather than violin and fly rod makers) have made them somewhat valuable. This one had the blade adjusted as low an angle as possible and had obviously been used backwards (knob in front) as a block plane. When I found out value, I offered to give back to seller but was told "good for you" and "does it look like I need the money?". Funny thing is, I bought socket sets, wrenches, etc., and 3 or 4 planes were thrown in (others are basically worthless). Not sure what I will do with it - likely it will pass on to one of my boys some day.
I would like to get an opinion on condition, and maybe help sharpening and setting up as a scraper some time.
