Definitely brings back memories, as those were standard fare components during my years in the field. And they weren't cheap either.
Seems like most of the rack manufacturers were partial to the Precision gang timers, and the Paragon's were in the minority.
With the Paragon you could replace an indivudual station, whereas the Precision was a single unit. Once a station failed, if you didn't have an extra station on another gang timer you had to replace the entire thing.
Worked quite funcionally as a timer for my sprinkler system.
