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.

$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
