Really looking forward to hearing from you all and getting this thing in top shape to do some viewing.

Do not clean the mirrors without reading lots and lots of stuff on how to clean astronomical mirrors. They scratch very easily; mirrors in reflecting telescopes are much more fragile than camera lenses and the same techniques that can be used on cameras cannot be used on mirrors. Do not attempt to clean them without understanding how to do it.
After such a long time the mirros probably need a recoating, this is not critical initially, but for the scope to perform it's best you will want to have this done.
It would be best to find a local astronomy club, members there would be more than happy to show you how to clean and refurbish the scope. That is, as long as you let them peak through it from time to time.
I noticed from the picture that the polar axis (RA for Right Ascension axis) has been put on the pedestal mount backwards. As it is, it cannot be elevated to align the RA axis with the polar axis of the Earth.
No doubt your Uncle had a bunch of eyepieces to go along with the scope - tryand find them.

Nice Christmas present...I'm not too 'up to date' (so to speak) on the Astrola Cassegrain design, but I'm guessing as a Dall-Kirkham, the sucker has around an f/5 primary and an overall focal length (with a convex secondary figured in) of around f/25. Probably has a minimum usable power somewhere in excess of 100x. Very nice planetary scope.
I'm now officially jealous.

Welcome to classic scope ownership! You've certainly got a fairly uncommon setup and hopefully you'll enjoy it for many years. You may need to get brave and take everything apart and do restoral on it. There is a Cave group hosted by Omaka Astronomical Society where you could probably find help from those who've done similar projects, especially since you may have problems in the mount that need looking into. My expertise is old Celestrons so I can't be much specific help, but check this group out...
