MF, I would be betting around 1991. I had a look at an old mitre10 shop book but they didn't do much pope stuff

I bought some galcon auto switching switching valves last year that were new but spent 10 years on the shelf. They came in a box that looked a similar vintage but had a 2005 datecode - retic industry moves slowly I suppose
