I have 2@ 9 x 12 x 56- 30 m/m tube specials about 10 years old , very good german optics, same quality as s + b etc as said they have gone out of buisness, the old man who ran it , died and unfortunatly no one was available to continue the buisness, I dropped one of the scopes last year, knocking the eyepiece off, sent it off to blackpool bincoculor centre,came back 4 days later, repaired,fully serviced ,nitrogen filled etc for £50 including postage , top job, buy them if you can.
