I talked to Ziess today,and I was referred to Cassidian - Optronics which is the LE/Military division of Ziess. They still manufacture scopes under the Hensoldt name. They asked me to e-mail some photos of my scope and check to see if it can be serviced by them.

Also found that Suddarth Opitical Repair will service early german optics. They quoted $95 to clean and reseal my scope. Although their main services are for binoculars and telescopes

IronSight Inc. quoted $105 with a 12 -14 month turn around. --------- GeezerD
