Broadhurst and Clarkson refracting telescope on non-original mount.3-inch objective. 4 eyepieces, probably Ramsden or Kellners. Mystery mount. Solid brass tube with black crinkle paint, 36 inches long. Approximately 40 inch focal length making it f/12 or f/13. All parts of the tube assembly are original. The focusing mechanism works perfectly. The objective lens is clear with no scratches, mold, or patina. It is important to note that many astronomical telescopes after about 1900 were finished with black crinkle paint. The shiny brass scopes most often seen today are a result of someone having removed that paint. I decided to leave the paint, and touch it up in a few areas where it had worn thin. You may choose to strip the paint and make it all shiny brass, which would actually look great as a decoration in your office or home.The equatorial mount does not appear to have been completed. It turns in right ascension but there is no fine adjustment and no gear at all for turning in declination. This “mystery mount” appears to be the work of a machinist at some point in the telescope’s lifetime. It looks spectacular and complex, but really doesn’t serve the observer very well for observing. There is one small gear that may have been meant for a motor drive, but there is no drive with this mount. Anyway, this scope is more suited as a decorative item than a scientific instrument.From my website - antiquetelescopes org: Broadhurst, Clarkson & Co. Benjamin Martin established an instrument business in 1750. His son Joshua joined him in 1778 and in 1782 he patented a method for producing brass tubing. The same year Charles Tulley bought the firm. His family owned the business until 1844, when it was bought and developed by Robert Mills who ran it until 1873 when he, in turn, sold it to Alexander Clarkson.Mr. Broadhurst joined the firm as a partner in 1892, but Clarkson and he fell out in 1908 and Broadhurst moved to 63 Farringdon Road, EC1, naming the building Telescope House but trading as \"Broadhurst Clarkson & Co. Clarkson had a top reputation and Broadhurst wished to trade on it. Telescope House produced very high quality astronomical telescopes from 2-inch to 6-inch in diameter. The building housed lens-making facilities a light machine shop and a thriving brass tube-making plant, using a brass drawing machine patented by Joshua Martin in 1782. This scope would have been made during that period.I did a search and found that a 3-inch Broadhurst and Clarkson scope similar to this one, but with an original B & C simple alt-az mount (non equatorial) sold at Christies’ for $8225.00. I am starting this one with a \"mystery mount\" at $1000.00 with ! Good luck in your offerding!Shipping to the continental US only. Original Broadhurst and Clarkson catalogue not included. The photo is intended to show how the scope was originally mounted. I will ship this in two or three separate boxes, well packed.
