1965 Gibson RB-250 5-string banjo (FON 366496).  Rim according to photos shows replacement with a prewar rim 9442-8 which would put it to 1929 and the beginning of one piece flange banjos.  It is unclear if the Mastertone label could be bona fide.  9441-1 on Greg Earnest’s site was a GB3, so this could be from a model 3 Mastertone.  The tone ring is a no-hole ring.  I personally get a bit anxious wondering if the ring could be a no-hole prewar ring added to this banjo, but most likely that isn’t the case.

Here is the Reverb listing:

This banjo–even though the ad doesn't note it–has a replaced rim. The rim in it is a 1929 prewar Gibson rim, most likely from a style 3. It also has a no-hole flathead ring, unsure if may be prewar itself (though unlikely).
