Click on the double-headed arrow and then scroll to enlarge the image.

Appears to load/unload from the car's end.

Built 1919.

Inflammable stencil.

I don't have any particular information on this car, but based upon the visible stencilled built date of 11/15 on the flat car itself, the most likely source was a CN 651264-651459 series flat car, originally built for the Canadian Government Railways as CGR 26000-26199. I see the "1/19" stencilled on the tank itself, which does provide a possible conversion date – given the unusual design of the tank, I'm inclined to think that it was specially built for this use, although one cannot rule out the possibility that it had been recycled from another use. The most recent reweigh is stencilled as "HQ 12/35", which translates to CN's Pointe St. Charles shops in Montreal.
