Base number B3011 is one of over 300 base styles used for lamps made by The Pairpoint Manufacturing Company. The B3011 is stamped below the classic Pairpoint P mark that is found inside a diamond. The top of the mark will say Pairpoint, Pairpoint MF’G Co, or some variation of that. Some lamp bases also have Made in U.S.A. stamped on them. Most of the value of a Pairpoint lamp comes from the shade. However, all collectors prefer to have an original base as well.
