Well, I have been dabbling in classic 35mm Pentax gear for a few months now and have discovered that Eric Hendrickson is considered the best in the business for that gear. Having just acquired an RB67 Pro S with a slightly mechanically flawed 127mm C lens, I have been searching for the equivalent name in RB repairs and yours seems to come up most often when discussing lens repairs. How can I get ahold of you to discuss the issue and repair options for my lens?
