I recently sent four older screw-mount lenses to John Van Stelten at The Focal Point in Louisville CO. The lenses had their inner optical surfaces cleaned of haze, etc. I was very happy with the service and quality of work. Turnaround was about 4 weeks and the cost was $75-95 per lens. I have heard of others having similar work done by DAG as well as Sherry Krauter's Golden Touch shop in NY. I was told by Leica USA in NJ that they decided in the early 1980s that they would no longer service screw-mount lenses (although they did repair my 1960 vintage 200 Telyt last year when the iris blades became dislodged). Hope this helps. Good luck! Corey Levenson Oakland CA
