It was a great kit, Jim, almost as easy as a shake the box Athearn freight car. Had her assembled in about 6 hours.:thumb:
Larry, the soldered brass frame, "Penn Line" on the tender shell and Muncy, Penn. address on the box date this kit to just after they aquired Penn Line in '63 but before their move to Montoursville in '65. They went to diecast frames in '88 and I don't even see the K4 on their kit kineup anymore, making it a special kit as I've always wanted one.
Once the drive train was assembled, I hooked it up to a 9v battery and broke it in for a half an hour in each direction, checking for binds and loosening screws as she went.
