I was about to reply but Wellplugger beat me to it.
Ii tried looking up Blackburn precision but cant find the thread I had for him, in any event Ted had got some serious health isuses when I last heard and was working hard to catch up with back orders, subsequently things had got more than a little dealyed.

The Sunny Hill products are very good, I have one on a Remington, but may be expensive to export to Oz. Best thing is to drop them a line with your exact requirements and let them quote you for what you need, IMHO they are well worth the money for the quality usually quality comes at a price.

I have never seen a Brown version but beleive their wotk is also top notch so worth a go there also
