I don't know how it is in the US but I would be on the lookout for a wreck of a machine with a spoked wheel. Dumpsters, old barns, even charity shops may have used up machines rusty and all on which you could salvage the handwheel.
I have a 127 with a mangled bed and a 15-75 which looks liked it had been used as a target for a medieval flail which I got for free and which I use as parts machines for bits and bobs...
