I am very confused I have this gun in Single barrel(which I can hardly find anything on), stamped on left side of barrel is LC SMITH OLYMPIC TRAP, and under forearm it has a OO stamp and below that says Crown Steel. Serial # is S108730. I can't figure out what I have as from researching serial numbers it says it was built in either 1901 or 1928 but if I read the Olympic info it says they were made from 1945 to 1950. Any help would be appreciated.
