I have a couple of old water tenders that would suit a roller or tractor etc.
In need of restoration but a good basis to start and would really look the part as they are old and on cast wheels with steel frame (one is part wood) and a steel galvanised tank. A big old tap is situated at the rear to enable buckets to be filled or showers taken !!!
The size of the tank is approximately 30 inches X 54 inches and using the following formula = diameter and the height of the cylindrical tank in inches 3.14xDxDxH/6912 x 7.5I guestimate the capacity at 165 gallons or 750 litres.
Asking 250-00 each and planning to visit Somerset Steam do at Low Ham so can deliver them to site.
Will upload some photos later (after I have worked out how to) or pm an email address and I will forward on.
