Well, here we go!

Remove the screws that you can see, the turrets, and the lenses on both ends. Push the innards out the end that you look in (ocular) and keep all your ducks lined out; take a picture! I used a fine glass bead, leaving all the tiny battle scars. I cannot say that reassembly was a slam dunk, but at least it can be described as an educational process; getting the holes to line up.
I was careful with the cross hairs. Very careful! I put the lenses back in and looked for the hairs and just about died! It appears that when the objective lens is removed it disturbs whatever, a sealant perhaps, in the threads. It formed a free floating blob that looked like mangled cross hairs; a real heart stopper! Anyway, after adjusting focus, the cross hairs appeared along with the blob. I put the objective end downward, slapped the scope, and the blob moved to where I cannot see it, just the very beautiful fine hairs and a small dot! I could go back in there and get that blob out, but that is not going to happen soon!
There were, at one time, two 1/16 x 50 tpi (I think), invisible, lens retainer set screws, one at each end of the scope. One had disappeared some time in the past and the other some where in this process. I expect I will use a needle and some jb weld to fill the holes...
I did not do the turrets, but have that option in the future. They are easy to remove and replace. An all steel scope is rather wonderful!
