Pen Model: Sheaffer Pre-Balance
Pre-Balance 1920’s Sheaffer pens have been commonly, but not properly, called “flat-tops”, for their flat-ended caps and barrels. Properly, they were called by their model names. They included Lifetimes, with the white dot, 14k trim, and Lifetime nib; “Regular” line without the white dot and with plated trim; and “Ebony” line, of black hard rubber, both chased and unchased. Lifetimes and Regulars came in hard rubber and Radite, Sheaffer's branded celluloid, in jade and then various patterns. And, there were 46's, a line of flat-topped clipped and ringtop pens made for secretarial use. These were made in black and bright scarlet Radite, and were very solid, well-made pens.
In particular, 1928-31 were very important years in American pens: the main shift from ebonite to celluloid. Parker and Sheaffer both made significant innovative and strategic shifts. 1928 marked the first appearance of Jade celluloid, and 1929 the first Balances. Sheaffer continued its production of the “flat-top” Lifetimes throughout the 1930s, but as of 1929 they were no longer the premier model.
