I've collected records since the 70s mostly heavy metal & hard rock. I've seen 45 adapters ever since I can remember but never really gave them much thought.

A couple of years ago I started focusing on 45s and ended up with several adapters I'd never seen before which got me wondering how many different kinds there were. This is the result.

If you have one I don't and are willing to part with it, let me know, if not send me a picture of it and I'll find one somewhere.
