Michael, welcome to the forum.
As a last resort you might contact Ron at Syracuse Industrial Sales, 1850 Lemoyne Avenue Syracuse, NY 13208, (315) 478-5751.
I don't think he ever carried this line but he has likely had someone bring one into his shop for repair and would have an idea where to get parts. Don't mind if he is a bit abrupt with you. Or opinionated. That's just his way. Just tell him that you had heard that he is the guy to go to. If you get a woman when you call that is probably his wife; tell her the same thing.
