It's been a long time since I've seen a question about a Western Auto Revelation air gun made by Crosman. First you will have to Identify it, the model number starts with GC3??? this identifies the crossover number to the Crosman model. With that you should be able to locate the proper parts for your gun. You can post the question with the revelation model number here or look up all the different Crosman models to identify your gun (See the link below for the Crosman owners manuals)
Once identified:
Crosman offers a free service to locate shops that repair older air guns. Fill in the information and it will give you the results. (See Link #2 below)
