I have found these.
Both will be restored, hopefully. The older one, in the foreground, has had a wrong tank swapped on. It should be a round tank like the other one. I'm pretty sure the early ones were green with red wheels, while the rubber tired ones were green with yellow wheels. I have one similar to the rear one, except with metal handles and it is a 1954 model.
