This is a throwback photo from 2003. This is a Sheaffer Triumph Sentinel Deluxe in green striped celluloid c. 1945-1947. This 5 1/8 inch long pen shows in the 1951 Sheaffer Complete Service Policy priced at $15.00. The Sentinel was the first Sheaffer pen with a brushed stainless steel cap. Note that the Sheaffer White Dot is on the end of the barrel. Sheaffer solved the problem of mounting the White Dot on metal caps in 1948. Sheaffer also changed the Sentinel to a polished stainless steel cap in 1948. This example has a barrel stamping of 1500, indicating the price. #pencollecting #fountainpen #sheaffer #sheafferpen #sheaffertriumph #triumph #vacuumfil #vacuum #celluloid #penhero https://www.instagram.com/p/B7mOMJzj_Ww/?igshid=d3x9qgyqeh76

This is a Sheaffer Vacuum-Fil lever-fill pen in grey and black striped celluloid in a spiral pattern c. 1935.

After introduction, Sheaffer treated Vacuum-Fil as a sub-brand and introduced lever fill models, such as this 4 3/4 inch long junior size pen. The Sheaffer name does not appear on the pen. The barrel imprint reads VACUUM-FIL over FT. MADISON, IA.

This is a Vacuum brand fountain pen in black c. 1935-1936. Vacuum-Fil was a Sheaffer sub-brand introduced in 1934 and the pens featured a new single stroke plunger filling system before it was applied to Sheaffer branded pens. This 5 inch long pen is interesting because of the following: it is a lever fill pen, not a plunger type, the barrel is stamped VACUUM with no other maker markings on the pen, and the nib is an unhallmarked two-tone palladium or platinum plated gold nib stamped VACUUM over MADE IN U.S.A. The nib is the same shape as the Sheaffer Feathertouch nib, but the plating is reversed with the tines staying gold and the bottom plated. Early Vacuum-Fil pens from 1934 have VACUUM-FIL stamped on the ball end clip. Sheaffer switched to flat ball end decorated and plain clips afterward, possibly 1935-1936.
