Hi Alex,
The Mak is for memory f/15 and comes with an older style 1 1/4" focuser. There are no coatings on the optics and its weight is 7kg.
Stefan gave some stats for Bill James, Australia's best optician who emigrated to Australia from the UK with his young family. He had a workshop in Camberwell and he has made up to a 40" mirror for someone in Tasmania (my memory is a little hazy on that one) - it was still on his work table when I visited him. He also remade the optics of the Govt 8" refractor at the Old Melbourne Observatory making exact test plates of the original glass to reproduce the exact figures they had even though he said that the design wasn't optimal. On my last visit there, he showed me the Mak and gave me a price for it, which I snapped at - $1000 some 20+ years ago.
Unfortunately due to the tube design, I didn't have a mount to put the thing on and still don't, so I have never looked through it in all this time.
I'll take some snaps of it over the next few days to show you.
