I picked up a cheapo Lionel 2757X cabin car on eBay recently. Yes, it's hard for some of us to pass these beauties up. The lettering is pretty good and the only issues are one coupler needs a hood, it needs a new sliding shoe, it needs window inserts for the 2 missing on the body and for all in the cupola, it needs new wiring and bulb and it was missing its cupola. Luckily, a visit to my cabin car parts box yielded an extra cupola, although it is red instead of tuscan. So, at one point, I'll be painting that.
Here are some pictures to start with. I'll post updates when I can. Feel free to post any cabin car projects you worked on.
