That's an MBF from the mid to late '50s, for sure. It's in beautiful condition, but the price is high unless they're rare in your area. I paid $75 for mine, although it needed some work. I agree that you have to count on replacing bearings, at least.Hey, I just got an e-mail. It's still available. Should I go for it?
The MBF is a great home shop size saw with around a 12" crosscut. It is almost unbelievably well made, from an era before disposable appliances. The only real weakness on these saws is the .75hp motor. They struggle with deep cuts ( 2"ish) in hardwoods and are limited to an 8" blade. If you're working with smaller stuff though, they're a pleasure.
I retrofitted mine with a newer, bigger motor, but that's a different story.
