Matchbox Lesney Superkings K 10 Scammell Pipe Truck Pipe Section.
These are individual plastic pipe sections. They are replacements and not a reproduction. The pipes are made by hand, assembled from two pieces of cut white plastic pipe, painted orange for the Superfast wheels version of the model.
As they are hand-made there will be slight variations in length (+/- 2mm) and there may be minor flaws in the paint - (I am trying to avoid that!)
Also available in grey, generally for the regular wheels model, and orange or yellow for the alternative Superkings colours.
