Anyone have an idea who made this.  Closest I found was a Parks but the castings and the way the legs attach to the pier are different.

Having trouble with attaching photos. I did create a photo gallery

Congratulations on recovering and conserving this mount. I would say late 40s to 50s era, but at this time cannot identify. Could be Cave or even Edmond Scientific.

Research through older Sky and Telescope magazines might find ads displaying said mount.

Doesn't look like the Cave mount I had, especially where the 4 bolts are near the pier. This could be a distinctive clue.

The Dec axis housing is an Edmund Super deluxe, as I recognize the axis brake. Nothing else looks too "Edmundy" though. The pier cap isn't Edmund at all, theirs screwed into their posts via pipe thread. The drives were much smaller and not covered as well. This could be a kludge as you can mix/match parts with a bunch of manufacturers so long as the bearings were all the same diameter.

 I'm pretty sure that is Coast Instrument mount. To post a picture you need to  go more reply opinions and then at the bottom of the page you can select a file on your device and attach it to the post.

I agree with Sean and partly with Davidg. The pier and legs are Coast Instruments Galaxy and the mount itself looks like a Edmund kludged with other parts. Plus none of the manufacturers I'm aware of have ever mated the mount head/cap to the pier like that.

The drive motor was manufactured in Nov 1957.  I looked at online Edmund catalogs from as far back as 62’ and the extra heavy duty mount declination axis looked the same.  However the pier was 4” rather than this 6” pier.  i also noted the saddle was different.   The RA axis looked more like the 1962 catalog picture and less like the 1969 catalog picture

Date on the motor may or may not mean anything - having had a clock shop for 30 years, I have seen motors replaced and replaced them myself many times. Sometimes I had old stock, but still new in the box, that was older than the clock; sometimes I could order replacement motors, which would make the date on the motor newer than the clock.

Considering that I will be using the mount for a 10” f6 Newtonian with Park’s mirrors and an aluminum tubing and rings cast by my grandfather, a mix of classic mounts is a perfect match.
I will have to fabricate some method to clutch the RA worm with the RA shaft. That is the next challenge

Identified the mount as a Spacek Instrument mount
