Welcome MacDaddy! Wow, I've never seen bent axles before. At least the coupler spring is in tact. How does the motor look? Does it run? May need a good cleaning, oiling, and new brushes? It's a surviver piece that may only need touch up paint to keep it original.

The first thing I did after the physical inspection was to disassemble, clean oil & lube. and the spring for the coupler and the Tender were both in the box which was fortunate and I pulled up a schematic for reference. This was almost like working on my Post War Lionel Fleet except in miniature. I also do HO so going through the progressions was pretty easy. 1. Test track, no power to unit . 2. Clean wheels, pickups, the Brushes were dirty but again in great shape, check connections did a Hot Wire from the Lionel 1033, Light works with minimal movement. 3. Deep cleaning, oil,lube. back on the using Lionel 1033 and it did run great except without the Marklin Transformer it wouldn't shift like an E unit on a Lionel so it ran in reverse....but boy what a shaker and mover. I also found a site on Ebay which carry's Revell Paints for touchup which I found referenced on the Forum. And I'd like to keep the wheels on the tender as they are in great shape and in line with the original piece and I've added the website for the wheels to my favorites. Pretty excited as the G800 is a Monster that could pull alot of freight. Now comes the collecting of the Track, Transformer and Rolling Stock! Thanks for your help!
