Well, my prize find is turning into a turnip. I am no expert, but I would have to say it has a chromed lined barrel and chamber. I read Bill Ricca's article on them and I can speculate that the part number for the chrome bore was removed from this barrel's bottom flat to deceive buyers. There may have been an import mark also removed since they were imported home from Korea. I guess it is a hit and a miss on the headspacing, if it is OK then all is well with the barrel. If it is not OK then the reaming of the chamber is in order and can't be done with the chrome lined chamber. So what is this turnip worth, anything?
