Hey Robert!!! You deleted your post between #53 and #54, no fair! May Mendy scowl. I'm left holding the bag of gullibility, except for the 'Shirley you jest'.
The mount alone as shown in entry #29, without the OTA, weighs in at a little over 500 pounds. The red counterweight is a single 90 pounder plus the threaded shaft. The weight is threaded like a Vixen Polaris style except it is very old square thread. The picture below is a cropped close up of that from entry #29. The 10" soda lime mirror in entry #52 above was found face down on a pillow on the couch. It was a pillow weight, understandable since it would be a way cool piece of glass to the uninitiated. The set latitude is 40 degrees, perhaps a fraction under. The motor is possibly 4-4-22 but that will have to be scrutinized by antique motor guys. DEC shaft is 2-5/8", RA shaft is over 3", RA gear is a little over 1" thick possible bronze, the RA worm is 1.9" diameter and 4.5" long, finder is copper tube heavy, drive linkage is a mass of copper/brass/bronze with manual chain. Very difficult to discern between bronze, brass, and copper due to age and patina. Green base, pier pipe, and RA housing are cast iron with "THICK" being the rule. Bearings are simple direct brass collars but with 2-1/4" deep bore shaft contacts on each DEC end, RA to be determined but appears to be similar. Brass bearings have external oil holes with internal channels for distribution, much the same as engine Babbitt bearings. The bearing thrust contact (flat face) is a decent size collar but I'm thinking a roller pin bearing with washer races should be added to the upper RA if not DEC as well. The DEC assembly is removed from the housing. The RA assembly is frozen into the mount and a real concern with potential 'one way' construction using pins and rivets - more on this later. The drive gear has been freed in the clutch and smooth but very gummy.
The primary cell is looking to be original but not a well ventilated design. I'm also finding glass chips emanating from the cell so concern there and total removal this morning. The mirror is encased in a full metal band around the edge with a rolled lip to hold the glass. This is very much like a modern secondary holder. The mirror plate showed no padding in previous pictures and small vent holes by modern standards. The aluminum back plate has no vents and seals the end of the tube off. This cell could be carved open but more likely kept original and replaced. Unfortunately the sophistication of the secondary has been lost. The spider is as previously shown but no glass or holder. It would be nice to make a secondary system with appropriate looks but modern functions. The finder works. The finder eyepiece is not original but that will get measured to see if the original might be around. There are parts that have been lost, tossed, or donated over the last 5 years. One loss (might be around) is a dual mirror set up that roughly fits the description of a heliostat. It gets into serious guess work from there.
