So I'm in the basement of an antique shop. I see a miter box just like the one in the original post(although a bit dustier) including the distton back saw. I walk back upstairs and say to the proprietor, "how much are you asking for the old Stanley miter saw?". He responds "^its not marked ?". "no I say". "Well, lets go look".
He looks it over, picks it up, moves it around, throws his hands up in the air and says, " how about $20".
I didn't have the strength to dicker.
