I just added another classic Zeiss to my collection. This one is a 1960s AS 63/840 semi-apo. It has an air spaced doublet and combination draw tube and helical focuser. Much lighter OTA than a Telementor.
The finder is from a Telementor II and is hence not original to the AS63. Would anyone of you know what finder was available for the this style AS63? The Telementor finder brackets are not correct. And, the 1940s and 1950s AS (with brass focuser) had finders that screwed via stem onto the OTA. I cannot find any information about what finder, if any, was configured for this style AS63.
