A lot of the big old industrial forges were oil fired. You need to ask grant sarver- he knows about them. Also I think the johnstown forge - cambria iron works- that kevin kreiger is working on reopening has some oil fired forges. Both of them read the junkyard- www.keenjunk.com/junkyard.htm try posting your question there. Although it seems to be down right now, but I'm sure its just a temporary server problem.
