I finally took the first steps in hunting down the right people to talk to about scope repairs. Cavalla had theirs done a few years ago and it took Kollmorgen a little while to make the repairs. So, in the mean time, I believe that the Navy loaned two scopes to them until the originals returned. Pictures are posted on the Cavalla board of the scope installments.
Until we get hydraulics working, again, I recommended to Rick that we modify the metal stands that the scopes rest on, now, and install ones with a kind of Lazy Susan to allow the scopes to rotate. Of course, we can no longer use scope shims in the housings, if we go this route. So, the stands would have to be much beefier, since each scope weighs about 2,000 lbs.
