In reguards to the 135 A Revelation,,, I am the Original owner of a 135A. I don't have the paper work for the gun, it was purchased at Western Auto in KY. I was 13 When I got it new. That was 1976, ****it, I'm getting to be a collectable. It worked well for along time, the seer has broken and it is on Full Auto. the barrel gets a rosie red when fired. I am trying to locate a manuel to order parts. I'm not sure if it has become a collectable yet.
