You're in the right section. I'm not going to be of much help to you as far as detailed info on your rifle goes as I don't know much about the older rimfires. I do know that Revelation was Western Auto's store brand and many companies made firearms for them to sell under that label. Here's a cross-reference chart that might help, but I don't see a Model 102 listed on it.
