It is Circa 1851 as this is the only date on the lantern.. The font is marked on the bottom "H & J Sangster - Patent - 10, June 1851" and this is definitely the Original Font to this lantern..
The lantern was made by the New England Glass Company as witnessed by the distinctive Chimney Vent Holes That only the N. It is a fixed Globe Lantern, that is, the globe is cemented in place and this lantern retains its original plaster-like cement in both the top and the bottom.. The lantern is very small and I believe it was not used in Railroad Service but rather, it was probably a Skater's Lantern.. It stands only 10 inches tall not counting the bracelet bail..
Please note the second photo with the lantern sitting next to a standard Pepsi Can.. The globe is "free blown" without a mold and therefor it has no seam markes.. The globe is what is known as "Cranberry Glass" which indicates it was made early when the only way to get a true RED color was to use Gold Salts to color the glass.. The lantern has been cleaned but the patina was not removed..It has been coated with semi-gloss Polyurethane Varnish.. This lantern has been in my collection for over 40 years.. Questions are welcomed and encouraged.
