$50-125, depending on WHICH rifle, and it's condition.
Western Auto sold several 22 long rifles. I need the model number to help identify it.
You need the services of a gunsmith.

It is a Marlin Model 49, made for Western Auto.
IF your Revelation rifle is a bolt action .22 Magnum, with a box magazine, it was made for Western Auto by Mossberg as their 640K model. These were made from about 1959-1985. Some of the cross reference data is a little fuzzy.....
CCI .22 Long Rifle- or any standard .22 Long Rifle ammo (there has been a major shortage of .22 ammo for a year now)
I believe that Marlin made their Model 49 rifle for Western Auto Stores using their Revealation brand.
