This is the first Sheaffer pen to use the Imperial name, the somewhat obscure Sheaffer Imperial Model AS9 c1960. The pen is similar in size to the Sheaffer Thin Model™ Touchdown Pens made from 1950 to 1951 but uses a later short Triumph or sheath nib that appears first in 1958 on Skripsert and Lady Sheaffer cartridge pens. AS9 translates to A=pen, S=Touchdown, long, and 9=9.2 karat gold Short Sheath Nib. The model was offered after the 1959 Sheaffer catalog and gone before 1961 when the PFM style Imperials were introduced. They were offered in Black, Burgundy, Blue and Sage Green. These 5 5/16 inch long pens sold for $6.00 and had a matching pencil.
