Rare 7 inch American Terrestrial globe "The EXCELSIOR" by Wachob and McDowall of Scranton, PA

Scranton, PA: Wachob and McDowall c1880. Seven inch globe with brass meridian and nine 3/16 inch mahogany laminate horizon ring mounted on an eight inch diameter mahogany pedestal. The horizontal ring is held by 4 brass uprights/spokes and is connected to the pedestal with a turned brass finial hub. Hand colored paper gores over a spun brass sphere with a tiny pointed bushing at each pole instead of a tradition axle and yolk set up. Bi-metallic thumbscrew with steel threads and a brass double knurled thumb wheel. The horizon paper is fragile and incomplete, pasted down to a thin 2 stage mahogany laminate. Cartouche notes "THE | EXCELSIOR | Manufactur'd | by | WACHOUB & MCDOWALL | SCRANTON PA" enclosed in a circle just below Alaska. Conservation work to the horizonal ring to repair an amateur repair and fix laminate structure (a conservation report will be provided to the new owner). Just over 13 inches tall. Near Fine.

Deborah Jean Warner, Curator, History of Physical Sciences at the National Museum of American History wrote a series of articles for Rittenhouse, Journal of the American Scientific Instrument Enterprise about what was then known (circa 1988) about American globes and their manufacturers. In Part II of the series (Rittenhouse, Vol 2, No 2, p. 61) she notes the following about manufacturer Excelsior School Furniture Co (1): "Under the proprietorship of Isaac Smith Wachob, this company was in business in Scranton, PA in the early 1870s. Only one globe is known, a 7-inch terrestrial amde of metal, with a metal horizon, meridian, and four supports, mounted on a wood base. 'The Excelsior, manufactur'd by Wachob & Medo(?) Scranton, Pa.' "

We are aware of one partial instrument sold at auction in 2017, and two in private collections. An extremely rare American globe.

Matt Jones at Green Dragon Bindery, who has restored globes for many years, notes this is an unrecorded stand and that Wachob used brass and other metals heavily in his designs. Matt also noted that the astute observer will see that the manufacturer positioned the meridian slots in the horizontal ring as if the normal mounting system (axle/yoke) was to be used instead of this new pointed bushing setup. This is clearly early in this manufacturer's experience making globes.
