long shot but spares needed

[MOW]

hi there
after my sip welder packing up on me ive been given a cheap mig and just want to use it breifly to finish the welding on the missus beetle...
the mig is the kind with the gas valve in the torch body, but this part is missing, just wondered if anybody had a scrap torch laying around, dont want to buy a new valve as the guy who gave me the mig said its years since he used it so doesnt know if it works anymore,have plugged it in and it powers up so fingers crossed

thanks

Make? Model?
Haven't got any bits but you're more likely to get a response if people know what you want.

Eeek I knew I had forgot something, it's a weldspares mig 100, don't mind if it isn't the correct valve for the model as I could quite easily adapt the torch enclosure or if the mig ends up to be working ok I will probably end up locating the proper parts.
Thanks
