Not sure Grumpy. It was replaced with a Honda pump on water cart about 15 or more years ago. So it could be older. My mate had it and was going to turf it. Still has the pump housing with it. I havent tried to start it as i am not sure what direction it rotates in and apparently it was running but a bit sad. So i was going to give it some love. Currently on my welding bench in the shed taking up space with a few covers and the manifolds off it.

I found the plate with the info in it but have not checked it out yet.

@Mower man, the old boy got a price and i think he pooped his pants. Not sure how it works with the Villers the Mk this and that, but its an old Mk25 with an updraft carb and its brass or something. For christmas last year i gave the old fella some Mk25 parts books and service manuals i bought from the UK on eBay. He still has his nose in them on boxing day. lol. He will sort it, the contraption its on is about 2 steps short of suicide to operate.
