I'm not too sure of its age, but I'd guess 1920s. As for value, it has none. It is rusty, incomplete, and has no base or cabinet to support it. I have over 50 vintage and antique sewing machines, but you couldn't pay me to take this one away.

Yes, it's value is zero. Even in good shape, it wouldn't be worth much. However, it may be worth a few bucks as scrap (and I'm not being funny).
