One issue with many Zeiss cameras is frame spacing being too tight. I am not certain which system this camera has. It might be set for thicker film and paper than is in use today. With a couple of these that I have had I ended up putting a small Post-It note on the backing paper right after getting it in the slot and this made the frame spacing good. Be prepared to run some tests. Should make a great car floor shooter!
The red dot system is for landscapes and vacation scenics. This might work for you, might not. Learning some rudimentary zone focusing is always a good skill to have.
No idea how many were made with the Tessar. Like the Super Ikonta III, similar but coupled rangefinder, the Novar was standard but every now and then a Tessar shows up. Nice catch.
