There are various projects on the windup workbench, but as far as actual restorations... this is on the "To Do" list:
It is a Marx 1935 clockwork swing-peg Commodore Vanderbilt. In addition to the work needed on the body, the motor won't wind up and run, the key is stuck in the motor and the wheel that has the governor behind it is falling apart from zincpest. Of all the issues, the wheel is the difficult one: Marx used 10 spoke diecast wheels for a few years, but only used the wheel governor for one - and that wheel is a different casting than the other 3 wheels on the loco, so it is next to impossible to find one. I think I have a plan to get around it, though. 
Should be a fun project!
