Most timers sold for photographic use are really industrial timers that have just had a new nameplate stuck on them.

In a turn-round, it sounds like this Kearsage timer was converted from photographic to industrial use.

As to the Polysales timer, from the looks of the age of the unit, and the rust on the screw heads, it may not be worth the time and money trying to fix it. Electronics that have suffered water damage are often unrepairable. You can get an old Patterson or some such in reasonable shape and for not much money on ebay.
