I have an older Kahles ZF-95 that belonged to the IDF and I would like to have checked out and repaired if necessary. I notice if the scope goes unused for awhile the turrets become hard to move. I had talked to Kahles and they didnt seem willing to to look at the scope but did tell me that is was made between 1966 and 1970. If anyone knows of where I could send this scope I would appreciate it.
