I have now put in the early type which is a little wider and sealed spot on without any polishing to my relief!
The R10 Mk1 was leaking through the reg. New seals throughout and bobs your uncle back to being a tack driver. I was a little confused that the new regulator seals looked a little different to the old ones but I think that was due to the old seals being in for so long that they had gone hard. The middle inner seal almost looked like a flat washer rather than an "O" ring but the new seals worked a treat.
Now my only problem is getting my scuba tank filled as its down to 200bar. Tried topping the R10 up with a pump...sod that for a lark...got about 10 pumps in before I could not get any more in and I'm a heafty bloke...nearly killed me! The Ultra should be OK with the pump though. Just my luck two guns sorted and running out of air.
