![Justrite Rubber Water Door Gasket.JPG - JUSTRITE NO. 907 WITH LIBERTY FEED - Brass cap lamp, 2 1/4 in. reflector, marked on side JUSTRITE PAT. MAY 7, 1912 PAT. OCT. 28, 1913 PAT. NOV. 23, 1915 OTHERS PENDING, with LIBERTY TRADEMARK water control and fancy rubber gasket water door marked PATENT PENDING, with reinforced bottom and rare banner stamp Justrite marking, Justrite model No. 907, excellent condition, acquired from my very good Alaskan friend Neil Tysver [Justrite introduced the Liberty Feed marked water control in 1919. The production of Liberty Feed lamps was short lived and they were no longer being advertised by 1922 pretty much corresponding to the departure of noted Justrite designer Augie Hansen in 1920 and his replacement with William Frisbie. Another new feature offered by Justrite during the Liberty Feed production was the rubber gasket water door with fancy engraving on the top. The rubber gasket door is not found in any of Justrite’s catalogs but was included in Justrite’s advertisements in both the 1920 (Edition #7) and 1921 (Edition #8) Keystone Mining (Coal Edition) Catalogs. The rubber gasket was only used on Justrite cap lamp models 907 (brass) and 909 (nickel plate) with 2 1/4 in. concave reflectors and models 967 (brass) and 969 (nickel plate) with 3 in. saucer shape reflectors. Justrite also introduced a new ribbed reinforced bottom in this same timeframe. This resulted in two rare base markings on these bottoms, one marked with a Justrite scroll banner and the other with a big J in Justrite stamping. The rubber gasket water door lamp with a Liberty Feed is usually found with a ribbed bottom with one of these stampings. The lamp shown here has the Justrite banner marking. The big J marking is shown on the bottom of a brass No. 100 superintendent-style lamp in my carbide hand lamp pics.
