I grabbed a Carl Zeiss Jena 8cm f2.8 Tessar for Prewar Exakta 66 mount lens.

First two pictures are of the lens
Last two are in comparison to a exakta mount.
Last is the pentacon 6 to fx adapter I bought. Seems to large? It just sits inside the adapter, the lens doesn't fit into the groves. What adapter do I use? Looking to use this on my fuji x-e2, thus x mount.
Here is the adapter I bought https://www.amazon.com/dp/B0096M53KU?ref_=pe_621110_204604710_shiptrack_e_304_dt_1









Thanks much

Perhaps I should ask.. can anyone make a adapter to go to pentacon 6? Or the like. I also assume if I could figure out how to make a 3D rendition I could make a adapter 3D printed?

Roger there are plenty of P6 to M42 adapters available.
Here is one:

Perhaps this plus an M42 to Fujifilm adapter will help

It has own Exakta 66 mount, you can't use straightforward any existing adapters.
According to this page register distance is same with Pentacon six
http://www.graphics.cornell.edu/~westin/misc/mounts-by-register.html
You can make a temporary mount from strong cardboard and fit into Pentacon six adapter
If solution is fine, give an accurate draw to a shop or person who able to print this mount plate to you
and you able glue plastic holder onto lens and into P6 adapter to make permanent solution what not hurt lens and removable if need
use semi strong glue

How do I know if it's the 6x6 version? They bring up a adapter.

"Exakta 6x6 - 1951
After the war, Willy Teubner, now as Technical Director, reintroduced the pre-war Exakta 66 at the 1951 Leipzig Spring Fair. Certain functions were updated, including an interchangeable finder, but production started based on pre-war parts[8]. The update also included a new Tessar 80mm f2.8 lens design from 1950[9]. Only about 300 cameras were produced post-war[10] The tooling for the pre-war lens mount was used to a much larger degree, however, as the post-war Tessar 80mm f2.8 lens in pre-war 6x6 mount was made in several thousand copies[11]. Later Tessar 80mm f2.8 lenses for the vertical Exakta 6x6 and Exakta 36x24mm actually contain the pre-war mount, adapted to fit. The adapter for 80mm f2.8 Tessar lenses to the Exakta 36x24mm mount can be used to mount any pre-war 6x6 lens to Exakta 36x24mm cameras, and furthermore to other adapters, e.g. to digital cameras. The focal flange distance for the pre war camera is shorter, however, so prewar lenses cannot focus to infinity without stopping down.
In the end the pre-war Exakta 6x6 was replaced by a complete redesigned vertical Exakta 66 in 1953 and later, with the Reflex-Korelle and Meister-Korelle, inspired the Praktisix and Pentacon Six models. Through these, the camera's influence can be traced as far as the Pentax 67 discontinued in 2011."
