If you need one to finish your 100% perfect, as original but better than it left the factory bike, then it's now time to make me an offer for this absolute gem of a find. You'll never see another one for sale* This remarkable artefact is a typical example of the breed. It goes 'click' when 12 volts are applied to the terminal and the solenoid moves and returns again when de-energised. With the solenoid energised I was able to blow through the fuel passage with some effort and it seals against my 65 year old lungs when switched off. The rubber diaphragm doesn't appear cracked or perished but may well be a little past it's best now that it is as old as some of you.
If you want this badly enough I have put a 'Buy it Now!' price of £10,000 on this little piece of loveliness. Alternatively if you are a resident of the real world you can make me an offer by PM. I will protect your identity of course. You know how rare and desirable this is!

*At least until another one is found and offered for sale-terms and conditions apply etc.
