The seller is a moron..... Skilsaw had been making their wormdrive saw for almost 4 years before that one was made. Skilsaw started production in 1924, that one was made after 1927. Not nearly the tool he makes it out to be..... I wouldnt pay more than $200 (I would be more likely to offer $50... old electric tools dont have much value) A neat saw, but nothing special.
Edit: another thing wrong was he said that saw was used to build the washington monument. It wasnt. A few saws made by that company were in repair work of the monument in the late 1920s....
I didn't think the price was bad if it were in as good of shape as he states. I was figuring pay 400 for it and then sell the bow setup to recoup some of the investment.
