Try gun shops, gun shows, want ad, for sale ad, estate sale, garage sale, on line auctions, egunparts.
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
this is pipe size dn100 ( Diametre Nominal 100) =100A
No because 100a-35 is an algebraic expression containing two terms.
