Yes the "dust cover" is made out of clear acrylic and has the "T'" handle in the center. My understanding is Cumberland (spelling?) made the first 6 + optic sets and Tom Scott made the last sets. Don't know this for sure though. I have been in contact with Jim Riffle and he is sending me "the definitive set of Astroworks/Astromak literature! I will post more when this arrives. The star diagonal elliptical flat was trashed and un-salvageable. The field flattener was not with the scope and may be lost to time. An inquiry has been made so a search is happening. We will see what happens although all is not lost in this regard. Jim says the optical shop that made these lenses is still in business and has the test plates. So one could be made. At least there are options.
Yes the corrector cleaned up nicely! That was my biggest concern. I was not going to sleep well until I knew this for sure. The mirrors will need recoating. When I get to that part it will be time to obtain some silver wire, fire up the vacuum chamber and once again put my government training to good use. The years I spent at Lawrence Berkeley National Laboratory as a vacuum deposition tech do come in handy! I will post photos of the "naked optics set" in the future as I begin to restore the tube assembly. The r and r of the corrector was to settle my fears of any etching that may have occurred. If you all noticed the threaded hole in the secondary holder Jim told me how to remove the corrector. Get yourself a 12 inch length of 1 inch aluminum bar, drill and tap a 1/2-13 hole in the end, thread in a 1/2-13 stud. Screw this into the secondary holder and use this as a handle to remove the corrector with secondary as a unit. It worked well! And YES, I am repeating myself.
