Replied to your pm mate....
There is a mob on eBay selling chinese knockoffs of the Dawes and needle valve. I have written to eBay regarding this, along with an email from the guy who designed and makes the dawes, but like everything with eBay. It just falls on deaf ears. So I made up a vid showing the difference between the genuine item and the fake.

I sell MAFs aswell. OEM and aftermarket. Not needed as such but a real good idea to keep a spare in the glove box. If the maf dies, the car more than likely wont go anywhere.
