The first Spotmatic was introduced to the public at the 1960 Photokina and became available for purchase in late 1964. It was one of the first SLRs to offer a through-the-lens (TTL) exposure metering system. The Spotmatic F is a refinement of the original.
If you need a new battery, you can get a replacement 1.35V from
WeinCell Batteries. The original battery was a, now banned, mercury cell. Also, check the seals common to the mirror to see if they are gummy. Cameras of this vintage often need some seals replaced. You should take it for a spin and see if everything is working and you're getting good exposure prior to actually needing it for class if you haven't already.
