Thank a heap for your advice.

I'm pretty sure that it's an andale fitting. But, it looks like the rttaylor mob have some fittings that will allow me to mate my corny up with this: http://www.andale.com.au/linevalve

And I'll keep the stainless tank mob in mind. Wish I'd known about these guys a few months ago!
