I was given a Sergent smoothing plane which is the size of a Stanley 4 1/2 C. It needs help, including a new iron, and the usual fettling, including a new tote. Does anyone here know whether this plane will be worth the expense and effort? By "worth", I mean either becuase of its value on the used market, or as a user (which is why it was given to me. If so, I will get at it; if not, then it will go in the pile of things that don't get done, which is already not a small pile.
