The lens has a flange distance of 122.09 mm. To install it on a Nikon 3100 with the focus on infinity, I used macro helicoid and a long extension ring M42 and adapter M42-Nikon.Mount to the Nikon

There are different versions of the lens barrel, with thread, the lens is attached to the enlarger and without thread. In my version of the thread was not, and had to glue it to the helicoid by an adhesive (electrical tape is better).

The lens has a nice, beautiful character.

 Bokeh also interesting, resembling oil paintings. I really enjoyed it. Frankly, I did not expect such a pleasant bokeh from Tessar type design.

Industar-55U 4,5/140 Contrast and Color Render

The lens has a weak contrast and backlight at all and does not copes a strong side light. Even its built-in lens hood, 25 mm long, can not help.

Backlight example

The lenses have a single-layer yellow-violet coating. Because of this, the colors are slightly yellowish. Color reproduction is nice, I would say vintage.
