My catalogue states that the rifle was made by Mossberg (Model 320-321) Mossberg made a variety of single shot and repeating bolt action rifles starting in the 1930. they were low-priced and were intended for extensive use. However it does not state when they stopped making these rifles. About 30 different models were made.

To remove the bolt from a Revelation 100A, first ensure the device is powered off and disconnected from any power source. Use the appropriate size socket or wrench to turn the bolt counterclockwise until it loosens. Once loose, carefully pull the bolt out, ensuring not to damage any surrounding components. Always refer to the manufacturer's manual for specific instructions and safety precautions.
$1,350 to $2,500 depending on condition. I did a search on the internet (eBay, Craigslist, etc.) and this is what the going price is for a 1974 Indian ME-100A. The guy who had the bike for $,2,500 dropped it to $1,950.
50-125 USD; probably 50-60's. Serial numbers were not required before 68 I personally have a Revelation Model 100A and i also have the Mossberg Model 340KA and the only difference is that the 340ka came with a clip fed magazine and the Revelation is just a single shot. As for the year the were made between 1955-1968. and for those who didnt know, the government didnt make gunmakers put serial numbers on the weapons until 1968. thank you
