The reader still works and you have never opened it for repair? Did a prior owner? I didn't think any of them were immune from gummy wheel disease!

I posted in this thread:

about a -67 I was actually using to repair a -65. The -67 looked like it had never been opened (smooth back label not a replacement), but the wheel was dark (rather than the usual golden color) and not gummy or crumbly. Still works (in my -65) today.

Btw the 45° card was from 65 Notes, as well as its variation with only part of the cut.
