G&S valves from Godalming, Surrey are considering producing a batch of Sloper 500cc OHV valves. Should be ready by about March 2022 and holding them as stock items. So any one interested might wish to make an order with them.
Very easy going and proffessional Co no delay in answering Qs etc.

I have confirmed that they are. I have a NOS genuine BSA sloper valve which has a tiny piled arms logo and the part number stamped on the head. As I live quite close to G&S the are borrowing it to compare and copy the unusual tulip form of the head of the valve.
