I sold this bowser a couple of years ago, it's recently come back in with along with the 4 inch Foster agricultural it was bought for - pictures are from 2007, condition is pretty much the same now as then.
A really nicely made passenger trolley/water bowser for a 4 inch scale traction engine. Runs on pneumatic tyres, the water tank is piped through to the engine via a 90 degree ball valve. There is a seat on the back and a spring-loaded drawbar.
Length 48 inches
