Do they still make Revelation model 120?
Well, no- and no. Revelation was the brand named used on
firearms made for the Western Auto Company. They got out of the gun
business, and then out of business- period. So, no, no one makes
ANY Revelation firearm. I THINK your rifle was a Marlin 99, and the
Marlin 99 has been out of production since about 1978.
