This guy we got here is a no.120 that's 7" long. The front knob will has a crack that can easily be repaired but is otherwise still a very usable block plane that could be put right to work after some sharpening. Its a "B" casting meaning that the casting was subcontracted out and that "B" is the foundry mark. "B" castings are more collectible and it dates 1899-1902.
All hand planes have only been cleaned and de-rusted to the point where the buyer can see the true condition and potential of the plane. They have not been tuned nor sharpened unless stated otherwise. (081)
