I realize my mistake now. I should have offered to go and look it over for kitsykeel and let her know if it was worth buying.
Kitsykeel, even if you can't make it run (which I doubt), for $25 you could use it as a parts machine for your 401. As I understand it, the 401 and 500 are mechanically very similar. I recently bought a 503 so that if I have to make any repairs to my 500, I'll attempt it on the 503 first. Sort of like making a muslin before making a shirt.
