Group, if anyone can help me identify the white tank car that is behind the 2-D+D-2 "*800 Class" in the two slides that were recently listed on ebay?

Builder, series, commodity, other photos of the cars would be helpful. Then a HO scale model, or kitbash start direction and decals. Any thing that can help in building a model of the tank.

Thanks
