As the others pointed out, those older valves are usually very simple, like a kitchen faucet. Some brands (eg Moen) even have a lifetime warranty on the cartridge! Probably your local hardware store will have the parts or can get them easily. Most likely this is just a dumb mixing valve and not pressure balanced. Code now requires pressure balanced so I doubt you could buy a new mixing valve style anymore (but parts for an existing one should be very available). One way to determine if it is a dumb mixing valve or pressure balanced: when it worked years ago (prior to water tank replacement), what happened if someone flushed the toilet? water goes hotter = dumb valve... or pressure drops and water stays the same temp = pressure balanced... Pressure balanced valves were introduced to reduce the risk of scalding.
With respect to how the shower was built: you always install a shower valve before the shower wall goes up, or from behind the shower wall after the fact. The valve does not ever pass through a shower wall during installation. It should be mounted to studs behind the wall (at least indirectly). If you need to take the whole valve assembly out, it comes out the back (and you normally have to cut pipes and resolder). That is why every shower should have an access panel behind it, or you end up cutting a hole in the wall on the other side of your shower to make an access panel when it comes time to change it!
If you just want to remove the cartridge/replace washers etc, you should not need to cut anything. You may want to soak things in CLR a bit before trying to open things up (think PB Blaster on a car)...
