Morning Arrow5,
You still after a 6v washer pump, apparently some early VW vehicles had 6v electrics. Could try VW specialists for one.
Finally made a start on the Superstructure. Building it my usual way ( making it up as I go along with no drawings

) and using 2mm balsa. How's that for keeping the weight low. I have built a Tyne style wheelhouse and will add some photos when I finish building the superstructure. Have also turned the wheelhouse into a big sealed box, Will put the batteries in prior to radio gear and test it's self righting properties

Shame you won't be at Wicksteed with McPuffer.
Clive :)
PS Nice job Willits. So how many Springers are being built now? And how many will be at Wicksteed?
