Lance Cross made this model of a Pintsch Gas tank wagon. Two of them Q26 and Q30 had the enclosed pump like this one; the other two (Q18 and Q27) had a full length tank and no cab.

Pintsch Gas was used for lighting passenger cars and many country stations had storage tanks that were filled from these wagons.

The 4mm scale model is built from acrylic and styrene with a brass chassis.
