KM20 oil tank on ebay, item number 386493899526,has original green paint on rear and oil drain plug same as the KM20 poster/chart thread.

What is the difference with the usual WM20 oil tank ?

I put that number into ebay and it said no exact matches found.?????

Hi David

Steve.S has provided the correct ebay UK ref. no. Try the full link below:

And this guy in Greece is selling what he calls a KM20/WM20 oil cap??? This looks like one of the Westwood caps as fitted during post war REME rebuilds.

The KM20 oil and Petrol caps have a bigger pyramid piece under the "T" handle than a WM20. Ron

Hi Mike, I don't think that the actual oil tank is different, but with that type of drain plug and the green paint it most probably was fitted to a KM20, I've never seen that type of drain plug before I saw the KM20 poster /chart.
