I just recently baught a single shot bolt action 22. The only marking on it is Revelation Model 100 22 S,L,LR Western Auto Supply Co. I do not know anything else about this gun other than it is in great condition, came with a BSA Classic scope and I only paid $60 for it. This is a great gun and shoots like a champ. I am wondering if anyone knows about what time frame this gun was made and who made it. I am thinking either Mossburg or Remington.
