John, the issue you will find
and the interior of the rolled rim will need treating. Both my rims are original and the hubs, I shy away from copies and much prefer original parts, but you need to be dedicated to restore them. Its easy to buy new spokes and nipples from RRC Tuning, bearings you can buy locally but you'll need the ring nuts from RRC and poss the bearing spacers. The rims will be full of corrosion, sandblast the rims, then drill 2 holes about 3mm diagonally opposed and tapping as you rotate with a rubber mallet the rust will pour out.
I'll follow with the next stage.

Original wheels
to an original drum if the wall thickness will allow setting up and machining to the radius of new bonded brake linings.
Before you spoke get the drums checked and machined for the new linings. Make sure you tell the spoker to file down the cut spoke end
without damaging the nipples, mine wasn't.
Goodluck.
Thanks
Pictures of rims can indicate the condition, but its not until you hold them in your hand that you can really assess condition. Maybe a visit to Veterama is necessary.
My concern I suppose is not seeing that inside rust and running the risk.
Once again, thanks for the response.
Regards
John

BMW R12 wheels
We have what we believe to be two original R12 wheels available. Both were apparently sand blasted before we acquired them and so have a light coating of surface rust. The brake friction surfaces of both hubs look good. The original bearings are still installed. The drive splines on one are excellent and perhaps 50% worn on the other. On our wheel balancing stand there is remarkably little vertical or lateral run out, certainly no real dents that would interfere with truing..
I have no idea where you are located, but if not too far from NH you are welcome to stop by to look at the two wheels. We also have a number of other R12 parts.

Brake drums
Thanks for advice
NH might be a bit too far for me to pop by. I'm in the UK.
But I bet NH is lovely this time of year. One day I'll visit maybe . . .
Thanks for the advice Spider.
I've bought a wheel on Ebay (fingers crossed) and we'll see when it gets here. It looks good in the pictures (famous last words).
Regards
John
