Thank you for posting the pictures.
Although the scope looks very familiar, the mount is very different. The one I remember had a much larger and longer horseshoe base. The ends of the "horseshoe" extended beyond the end of the cradle of the mount (it also looked like it was metal cast). The entire mount was painted in the same "sand" color as the end rings, focuser, finder scope rings, etc (BTW, you can use RUST-OLEUM Satin Fossil paint for touch ups). The other thing I remember is that the controls were placed on a panel on top of the RA Shaft and the "bones" of the drive unit was nicely shrouded with some sort of case (probably to hide the Astro Works drive as it would have been 2 to 3 times the cost of the scope and dominated the branding, I distinctly remember this as in the mid to late 80's, I made many trips to Edmund in Barrington and always drooled over this scope. At the time I didn't even own a camera (film only back then).
Your mount may be an earlier version, used as a display and then replaced by what I remember. The good news is that you have the same Astro Works mount and the horseshoe base on yours is much more compact.
I do see that there is an extender tube on your 2-inch focuser (I have the same focuser and invested in extensions f various lengths) which are needed for any FL eyepiece to focus but this is great for using a 2-inch filter wheel (just remove the extender and replace with the wheel). Where's your finder scope? I can assist to identify what came with the scope (one of the items I paid full price for due to the fact that it was sold with other scopes and as a separate stocked item).
I had great difficulty finding any dust caps that would fit the OTA, especially due to the taper of the end rings. Did you get dust caps supplied with the scope or do you have something else?
I'm thinking that there is at least one more out there (not twins but triplets)!. We should form a very exclusive club!
