Identify Camera and lenses

[Newagetofinders]

I recently bought a box of interesting old cameras. I was drawn to the strange attachments I could see. I tried to do some research but could only go on what I could see printed on the items so came up quite blank. I found a Taylor Hobson Anastigmat 2 inch T2, when I looked up this lens the closest I could find was an F2 model in silver so maybe my lens in black was for something other than an slr camera?. I found a Zenit which looks to be custom made model with a strange optical hose attached to back. Please help me identify these things I’ve added photos. Thank you

The Taylor Hobson lens may be an old movie lens, given it is T-stopped, rather than F-stopped. The engraved words about the Tricolour process perhaps give another clue. The big cylindrical thing may be part of an oscilloscope kit. As for what's going on with the Zenit body, I have no clue. It appears the film transport mech is missing, but the shutter can be cocked by the lever on top? Interesting stuff.

I agree, the mounting ring with the screw holes suggests to me that it is for a Gun Sight Aiming Point camera

Camera looks like an FSU motorized Zenit for surveillance work and a DDR made telephoto lens by Jena Zeiss or Hugo Meyer/Pentacon.
