The focuser is a Meade. I imagine it is not original to the OTA. I'll post of picture of it shortly.

And here's a picture of the mirror. Don't mind the water drop. It's drying now. To my untrained eye, I don't see any scratches. The surface is not pristine cleanliness wise but I would prefer to err on the side of not touching it rather than risk scratching it. It's definitely thick. (1.75 inches at the edge). There are no markings that might indicate the maker. Is there any way to determine that otherwise?

No scribeings on the edges / sides ? Sometimes these can be very faint .

OK, the one thing I did see was the number 56.3 on the side. Nothing on the back. Rats! I guess it's not a Cave.

Most definitely a Cave Mirror Cell . A un marked 1.75 " thick 10'' F 5.6 mirror still could be a Star-liner mirror in a Cave mirror cell .

Yes , Star-liner would be my guess for the Glass mirror , and Cave for the cell or holder for the Glass mirror ( forsure ) .

Interestingly, there are three pennies hanging out in the cell.

 

Detail of Mirror Cell

 

Should there be something like a little felt between the cell and the mirror?

Optic-Craft used round knobs on their drives, you might have a look

though here and see if anything looks like yours:

Thanks Robert! So was the purpose of the knobs to simply facilitate turning the driver manually or was there a different purpose?

The knobs are for the clutch, you can tighten or loosen these knobs to adjust the pressure on

the clutch to get just the right amount of grip/slip so you can move the telescope tube, let go of

it, and the drive will resume tracking.

I'm still learning so much. Looking at the drive assy I knew there were plates but didn't even realize they were a clutch mechanism. Now looking at it, it seems obvious. Since this does not appear to be the original drive assy, I wonder if it might even be an older opticraft.

 

I don't see anywhere on the opticraft website that they have listed replacement parts.

There is definitely a similarity though mine only has one motor on it currently (though it looks as though it may have had another at some point and if it ever had a controller it's not there now. I don't see anything on the drive itself that identifies the maker (other than the cap on the Hurst motor). Perhaps once it gets pulled off for cleaning and refurb more will be revealed.
