Vinegar Tanks

Dave & Libby Nelson <muskoka@...>

In 1950, the Soo had 4 cars classed TW: 4481, 4491, 4669, and 4799 - all
marked as vinegar tanks. I'm wondering if these 4 were rebuilt from another
series of cars: 4401-4799 (they share the same exterior length) or were they
oddballs in their own right?

Anybody know?
