I found one of these in some old Lionel trains that I rescued from the attic of my in-laws 35 years ago (and am JUST now getting to them LOL) that no one knows any history of. There are no less than 4 nice steam engines most completely disassembled with parts all mixed up all thrown loose in a box! I have thus far been very successful in restoring a 2037 and a 2026 to their full glory. These engines all seem like they were picked clean by Morlocks! Just senseless and COMPLETE tearing them apart! The darn 2026 even was stripped of its handrails! I am now working on this 1666. The motor was removed and I'm not sure if I am missing any pieces as I cannot figure out how the motor is held in place. I see where it attaches at the rear but can't figure out what holds it in at the front end. I found the engine in pieces and am trying to restore it. I can't find any diagrams etc. on the net. This one is REALLY in pieces the wheels are off etc. But it seems like it is almost all there. I ordered some e-unit contacts which were missing and am still looking for some side rods. But I can't yet figure out how the front of the engine is held in place. I see it was not a smoker. I know about quartering the wheels etc. I just need to see what holds this motor in place. Any clues would be appreciated. Pic of inside of shell attached.
