The weekend is over and the scope has survived, striped and cleaned reblued and working perfectly, the scope was that dirty that it was like looking through a toilet window, the turrets were sized solid and the recital was missing.
First a full strip, tube dipped and cleaned, cleaned all the lenses, solder in a new recital (headache & a bottle of optrex later), focus the recital and then set the image/parallax with shims. The only thing I did not get around to doing was the outside finish of the turrets I just ran out of time as I wanted to pop do the range to see if it worked, result 2inch group at 100m
