Thank you from a newbie looking to buy a classic refractor.

here is a close up
These are beautifully made scopes. My Wife and I were fortunate to acquire one reciently, however, have had little chance to use it with the bad weather here in the UK.
I notice in your photos that your mount doesn't seems to be supported all the way down on the tripod pintle. Our pintle is 2 3/4" long and fits into a 3" deep mount socket.
Here's a picture of ours for comparison.

mine is Telementor II with internal focuser, the mount looks exactly like yours. I got the lens this summer from my friend. The OTA was very difficult to use:
Still I had some fun with it, both on DSO (here) and planets:
The views through the lens were charming and it definitely deserved better OTA.

If you look at the picture from Mike E that is a telementor II. I think you have a Telementor that dates before mine which places it before 1970.
The lady we purchased it from, said she bought it new from her local camera shop around 1980.

I noticed that also. Will check into that tonight. maybe just needs a little cleaning..
Inside the mount socket, there is a recess in front of the locking screw which has a metal plate in it. The screw pushes the plate against the pintle to lock it in position. Perhaps the plate is not backed far enough into its recess to allow the pintle to seat; its a close fit.

OK. thanks for clearing that up. You had me confused.

The Zeiss Telementors were made from mid 1972, with a helical focuser, until around mid 1979, when they were replaced by the Telementor 2 (1979-1994), with the interior, crayford-style focuser, which only moves the objective. A very unique and brilliant design. Even very heavy accesories can be solidly attached to the rear end via the M44 threads. It has a bit more back focus than the Telementor 1. From around 1981, one could also buy the Telemator, which was a Telementor 2 with 7.5x42 finderscope and upgraded T mount (to model TM) with motor drive. These accesories could also be purchased separately, so one could upgrade older Telementors to motorized versions. The finderscope can be used on the Telementor 1, but doesn't fit well and is rather awkwardly placed on the helical focuser. It is primarily designed for the Telementor 2/Telemator.
Eighty years of Zeiss history. From right to left:
1910 Zeiss Reisefernrohr, 1972-79 Telementor, 1989 Telemator
The above image shows my three Zeiss 60mm's. The tripod on the 1910 Reisefernrohr is not original, but the Telementor and Telemator are 100% original. The Telementor doesn't have a tripod accesory plate/tripod brace, which is a major design flaw, IMO, since the legs can slip if the ground is slippery, from ice or such, and then the scope tips over. The OTA has a dent in the dewcap, so this has happened at least once in its past.
The C objective of the Telementor/Telemator series is a cemented achromat. Nothing fancy at all. I've seen two with a little astigmatism (one actually has quite a bit of it, it's the Telementor seen above) but the Telemator has a stunningly fantastic objective that will take 336x on double stars. What's scary is that the 1910 Zeiss is visibly better! I have since mounted a Zeiss dovetail on the Reisefernrohr, so that I can use it on my TM mount, which is a lot more stable than the original mount and has tracking to boot.
These are small scopes, for sure, but they have terrific optics, so they can show amazing things.
