I used the belt tensioning tool allot checking the tension on ventilation fans with multiple belts, at the power plant during my career.

I also have a couple of the fish gauges. They are used for threading on a lathe. They help to grind perfect 60° threading tools, set the tool perpendicular to the piece threaded in the lathe and give dimensions for the depth of thread for a particular thread count. Kind of like a carpenters square for machinist.
