I've only been in a couple, so I'm no expert. In general I think, if it's not locked then there probably isn't much to see, and even the locked ones are often quite empty. There are exceptions but they are just that. I really enjoyed tracking down my local post and having a look, but I can't help but get the feeling that many are in the same state of emptiness/moldiness. Definitely have a look though, if only to sate your curiosity! All you need is a torch, and possibly wellies if it's wet.
