Oil the thing up good and see what happens.
If all else fails, it has good top hats, throat plate, bobbin slide plate, motor & it has a good zig zag foot etc. Some of those parts will work on a 401, 403, 500 or 503 or maybe some of it will go on a 301...
The body of it probably has some aluminum in it and you probably can sell the manual on ebay...
I never did like those... does it show?
