I recently purchased four lionel engine shells. two 1656, one 2055 and a 682 turbine .
When I received the shells I looked over the 682 shell, noticed it is an original 682, as I looked closer I noticed the holes that the boiler front, railing, and oiler linkage didn't have any marks showing it had any parts put on it. Also there is no 682 numbers on the cab, close look it appears that it never had any numbers stamped on it.
I would like to hear from the experts if this could be a NOS shell.
