Wow, those are cool. I have a Craftsman Bandsaw that was built in 1952 that could sure use guides like that.
My dad bought the saw in 1959 from someone who told him it needed a motor. I think he paid about $25.00 for it. When he got it home, he was looking it over and saw a red button on the side of the motor. He pushed the RESET button, and it has worked fine ever since.
I had to put a new tire on the top wheel last week. I went to Sears to order one and the guy behind the counter pulled up a parts list from when the saw was new. In 1952 a new tire was 75 cents. A new tire today was $12.50.
The saw is still working fine though. I just finished cutting 160 pieces .250 thick from 2.375 diameter aluminum bar.
