I've been on the trail of this telescope for the better part of a month and I finally got the opportunity to purchase it today.
I'm assuming right now that it's an RV-8, but I'm not sure what Criterion's 8-inch Dynascopes looked like prior to the launch of the RV line. I'll need to start researching. There are no model markings anywhere -- no plaque or serial number. I haven't opened up the drive yet, but perhaps there will be a date indicator on the motor.
This telescope has seen better days. The mount is in rough shape, both in appearance and functionality. It's stiff and rusted everywhere and the slow motion controls seem pretty messed up. The paint is gone from the focuser, the rod is bent and missing a knob, and it feels pretty non-functional. It will be a long restoration process for me, but that's okay!
The tube is in great shape and the mirrors seem fine. Very dirty, but no apparent damage. Although I haven't pulled the cell out yet for a close look.
The finder is an 8x50 beauty! And the telescope came with two Orthos: a Criterion 4mm and Edscorp 25mm. Nice!
All in all, I'm delighted. Here it is with my RV-6...
