Classic Contax Lens Repair?

[wjlapier]

I have a Contax lens I'd like looked over and maybe repaired. Who now is the repair person to send a lens to? Glass looks good. Mechanically, it seems fine. But something was brought to my attention that the lens was disassembled and not put back together properly. I would have missed this.

Thanks!

I thought of Don and have used him in the past but wondered if there was someone who specialized in this lens type.

Thanks though.
