What dump valve is this and what's it worth

[jrracing]

If it is a genuine one I may be interested providing twin piston etc...

Its an obvious immitation Forge, it would be engraved or embosed with Forge otherwise.

Worth square route of FA!

[Mawbster]

I think its worth a gazzillon.

But. I like collins better. And as dan says if its blank its an immitation.

However thats not to say it wont work perfectly fine.
