It's unlikely you will get one that is a perfect match though it could happen. I would suggest having your Tech knock one out and be done with it. If he has the tooling and good skills, he should have it knocked out, fitted and up and running in under two hours. Not as simple as the unlikely event of having a used one show up in the mail that is a perfect match but at least you will know that the one your guy makes will be exactly what the doctor ordered. Good luck with the project.

Buy brass stock yourself. It's not that expensive, even if you have to buy a 12"-long piece of round for the rotor plate.

Perhaps you haven't bought any brass stock that diameter recently. Small diameter brass stock is pretty inexpensive, but as the diameter increases, the cost goes up exponentially. But, if your machinist has the stock, that would be a great option.

If not, Jason my be able to save some money by contacting Amati USA in New Jersey and purchasing a rotor back plate from Amati-Cerveny. I have found them to be friendly and accomodating.

Yeah you might have to order more then you need but still, if you are going to be in the business of repair and restoration, its not real costly. The labor is what sets you back. Thats why having a lathe in your shop and the knowhow to put it to good use is so important.

Turned parts: buttons, caps, bearings, stop-arms, stems, ferrules, rods and screws, levers and linkage, hinge-tubesand shafts, boxes, tenons, crowns, lids, posts, sleeves, saddles, cups, draw-knobs, rings, rims, etc. Learn to make em or pay someone else to do it for you.
