During the Depression many pen companies introduced lower priced models so as to not detract or lower the prices of their existing models. For example, Parker introduced the Thrift Time, Conklin started the All American brand, Esterbrook introduced the Dollar Pen and Sheaffer introduced both WASP and VACUUM-FIL. UNIVER (circa 1930) and CRAIG (circa 1912), other Sheaffer sub-brands, were introduced earlier. CRAIG was Sheaffer’s son’s name, WASP stands for W.A. Sheaffer Pen, CLIPPER was named after the Pan American Airways China Clipper airplane, UNIVER was likely a shortening of an earlier sub-brand, UNIVERSITY (circa 1912, described as a coin-filler pen). To save money, many nibs were stainless steel, those which are gold (all the nibs below) are 10K rather than 14K.
