This is a Lionel 6-52051 TCA Baltimore and Ohio "Sentinel Service" Box Car.  It has "The National Toy Train Museum"  on the side of the box car.  It is a Limited edition car, highly detailed.

It is in Excellent condition and has only been out of the box for the photos since I acquired it.  

The box is in Excellent condition. Please see Photos of the item and the box.  I am selling this from a large private collection that I inherited and it needs to be downsized.  

Shipped with USPS Priority Mail unless you choose Ground Advantage. 

Thanks for looking.
