Bill filed notches into the bottoms of each leg and the base of the pier. One notch for the first leg, 2 for the second and 3 for the third. I think his intention was to ensure the same leg went in each position each time. This probably allowed quicker polar alignment if nothing changed between setups. Also, the notches could be easily felt in the dark.
You'll notice in the photo that Bill attached a cotter pin to a string on each leg. The pin fits in a hole drilled through the leg and pier. The purpose of this really perplexed me. I think the user would insert the pin and expand it inside the pier to prevent the leg from falling off accidentally if the pier was picked up and the thumb screws holding the leg on had loosened up. Just a guess.

Moving up, there's a nice little wooden shelf for 5 eyepieces and a barlow. A small pin keeps it horizontal and a spring wraps around the pier to hold it there. I don't have a photo of it but there's a piece of red vinyl that attaches to the pier above the shelf to keep dew and dust off the eyepieces.

Jumping ahead in the resto process, I'll show the mount. It consists of 5 aluminum castings. They are very nice with little porosity and good thickness. They remind me of the Russell Porter castings (many bronze) that I ogled as a kid at Stellafane.
Only problem is the machining of the plate where the tube rings attach made the metal too thin and it cracked at the hole for the rear ring. There are small blocks that provide backup for the bolts that hold the rings to the mount.

The mount comes apart pretty easily.large knurled rings on the rear of the polar shaft and bottom of the dec shaft unscrew and the axes come out of the bearings with light taps. Bearings are ball, no tapered rollers here. There's a piece of white plastic that serves as a thrust bearing on the dec axis and the clutch behind the RA gear is a red plastic (phenolite?) disc with 30 steel balls set around the circumference. Tightening the knurled knob puts tension on the RA axis. The thumb screw tensions the dec axis.

The block that supports the worm gear is shimmed for backlash.

Tim, As I posted above, I agree that Mr. Ballas might have been an amateur that ground the mirror and had Bill make the rest of the scope. However, the dates don't quite add up... Maybe Mr. Ballas is the gentleman to the left of Bill in the Charlton Flats photo. Anybody recognize him?
Paul, I didn't start going to Charlton Flats star parties until 1960-1961, so I can't say that I remember Mr. Ballas. If I knew just a little more about him - like his first name and where he lived - I might be able to identify him from the numerous Ballases that show up on the many California databases on Ancestry.com (for example, voter registration lists, street directories, and birth, marriage and death indexes).
I'm attaching a photo I took at a 1961 star party at Charlton Flats.

I just dug up this picture from my personal archive. It's from a December 11, 1960 newspaper article about Tom Cave the Mars observer. He is shown at the eyepiece of his personal scope, a 12-inch Newt. mounted in his backyard observatory. (I'm pretty sure that Alika Herring made the mirror.)
I had the privilege of looking thru it on one or two occasions in the 1958-1960 timeframe when I was a guest at one of the meetings of the Excelsior Telescope Club held at Tom's home in Long Beach, California.
Note the mount: it is not an Astrola but appears to be a Bill Schaefer designed and built equatorial head - correct me if I'm wrong. (Also note the telephone wires strung over Tom's backyard!)
This scope was something like an f/7 or f/8, so Tom needed a stepladder or observing platform to reach the eyepiece. In this photo, he is seated on his observing platform for comfortable viewing.

Hey Lew, Those are great photos of Chilton Flats and of Tom Cave's telescope. With regard to the similarity of Mr. Cave's mount to a Schaefer design, I refer the reader to Larry Adkin's Tom Cave website at: http://www.cerritos.edu/ladkins/Cave/thomas_cave_observatory.htm Larry also has recognized the possible connection with this early mount.
Also, the original post about the ebay Schaefer telescope indicated that the seller bought the scope at garage sale in West Covina. Maybe Mr. Ballas lived in West Covina or nearby.

Just a few photos to update you on the Schaefer progress. The mount is reassembled with clean, greased bearings. The optics are in the tube. It's looking great!

The next challenge! The motor does not turn but it vibrates like a synchronous motor does. Some reading online indicates that the typical problem with these is that oil in the gear reduction dries up seizing up the little gears. Looks like I'll be opening this thing up next.

Finally, can someone help me ID this plug? I need to buy the female plug end and it would help to I knew what to call it. As you can see, the 2 conductors are skewed at an angle and there is a tab on the ID that only allows the plug to go in at one orientation.

The ID of the hole is 11/16" and it's about the same deep. Ant good websites for electronics where I'd start looking?

Wow!
That is looking NICE!
I wish I was more knowledgeable about electronics (my dad was the electrician, I'm the geologist!). But I'll bet that a good electric motor rebuilding outfit could restore it ...for a price, of course!
I eagerly await more!

Outstanding thread Paul! 
It's absolutely wonderful to see this scope coming back to life - even better than the original! Thank you for your commitment to this project and all the research and hard work you've invested into this Schaefer.
Great documentation. I would recommend that when you have completed this project that you submit all of this as an article / review to Cloudy Nights. They have a classic telescope section for articles / reviews.
