I think Tony is in the shed fixing another Wersi...
Ian's right the shed is full of old Wersi parts, there was a Wersi Helios breaking for spares on Ebay yesterday, it looked in perfect condition on the photo but that don't mean a thing with Wersi, thats the reason for breaking it up, it don't work anymore..

Go Go Go Wersi down the breaker yard. A good A

bacus will last you a year longer than a Helios...
