This set followed me home from a show near Toledo, OH this afternoon. I believe it's a partial Lionel 1091(?) set from 1938 consisting of a 1666E locomotive followed by a 2689W tender, a 2679 boxcar, a 2680 tank car and a 2682 caboose. Unfortunately I'm missing the boxcar and there don't seem to be too many 1938 ones out there at the moment so I'll have to keep an eye out for one. The 1938 ones had nickel plated journal boxes whereas the later ones had blackened ones. I haven't serviced the locomotive or tender yet, but I don't suspect they'll give me much trouble. At the very least, the locomotive will need new pickup shoes as the original ones are pretty worn. The original locomotive paint is in very nice shape as is the paint on the freight cars. The tender is a bit worse for wear as far as paint condition, but not the worst I've seen.
