Univox U3R, Pro Verb, Spring Reverb, 2 Channel Input, Vintage Unit.
Vintage reverb unit made in Japan, from the 1970s.
I tested the unit (all 4 inputs), it works fine. The bottom right input of Input 2 is quiet; however. I ran it through a twin and it sounds amazing.
There is some wear and tear (please see photos); but, for being 50 years old, this thing works and looks great.
If you have any questions, feel free to ask. Thanks for looking!
