To those interested, I contacted a group in England who makes reproduction Rudge wheels for the D-types, MGs, etc. Apparently they used to make the wheels for the very nice 300SL replicas made in LA many years ago, the company Mercedes shut down. Anyway, they have the designs to make a 15x7 Rudge-type wheel (same dimensions as the wheels on the Bohringer car) out of aluminum. I suggested a look-a-like with a wheel cover so that one doesn't need the axle adaptation kit. Cost is expected to be just under 4k for a set of wheels. So if you know any 300SL owners or 190SL owners who don't want to pay 40k+ for a set, let them know. I am asking for the weight, as this isn't something I'd be terrifically interested in if they weigh over 20lbs. Will update with that information.
