Just wanted to update the story- I was able to find the correct parts for this machine on eBay. Haven't run it yet- I still need to adjust the motor and rebuild the reproducer, as well as get some needles and records.
Thanks to JerryB for selling me the appropriate gold crank, sending me some free reproducer gasket material, and for all of his help with identifying parts for this Victrola neophyte.
