I have a decent set of 6 -19" lock ring style wire wheels. Of course I only have 2 lock rings
Check out Coker. I think they will make them. Pricey, I bet.
These folks may be able to help, they are a bit away however. I bought 4 new lock ring style rims for my Dayton wheel project from them. Very nice quality.
Vintage Rims are quite close to the epicentre of the recent earthquake.
