O boy, I get to make the first real post!
I have been looking for a good rabbet plane for while now. These things are pricey when you can find them. Learned of the Stanley 140 and really liked the block plane design. Like the skewed blade since I often angle my block plane too. Plus the fact it was a rabbet plane, I knew I had to have one.
This came up on Ebay and I assume since the knob was missing, it went (what I considered) reasonable. I guess the collectors didn't want it. Since I want to use it I don't care. I will just turn one that fits my hand.
