Thank you Roy and Others for shedding more more on all steel barrels made basically the same as damascus-by forging. I became interested is this process after reading an old catalogue on Belmont (Bonehill) guns. Barrels were avaiable in various damascus and "3 Bell Steel". In my research, steel (not molten) went through 3 furnaces to make it more "pliable", I guess annealing in 3 steps would be a good decription. Since it wasn't "poured" I suspected that strips had to be forged together and you've confirmed that idea. Only a suspicion but I think I have a set of all steel forged barrels by Bonehill-I guess trying to get a damascus pattern with out succeeding would give a good indication, looked at close it looks like very fine twist. Any marks I could look for, the barrels have a 3 on them but no "steel" mark? --- John Can.
