0 ITEM #5120: PARKER VACUMATIC DESK PEN WITH FLEXIBLE ACCOUNTANT NIB.
Very clear ink view pattern - see the CLEAR-O-GRAPH photo below.
The smart new arrow clip was fixed to the top with a handsome jewel screw, and a similar bit of trim was found on the blind caps of most of the earlier Vac models (the arrow clip and top jewel would remain a Parker hallmark through the 1970s).
The best of the Vacumatics are the top-line models of the '30s, as illustrated above.
The filler units are all-metal, the nibs are two-tone, there is a "jewel" and tassie ring at the end of the barrel, and both jewels and the section are laminated (at the end of the decade, many pens came with nonremovable "bullseye" barrel jewels, which appear black in light that is less than bright).
) In the introduction to this series, I mentioned that one of the drawbacks to the various sac-filling pens was ink capacity.
Because you need room for the sac itself and whatever is compressing it, there's a limit to how much ink you can get into a sac-filling pen.
Sample shows the backside of the page which has barely any ghosting.
Hope this helps those looking for decently cheap paper.
Eventually, Parker settled on the zippier model name "Vacumatic" (the suffix '-matic' being to the 1930s what the prefixes 'e-' and 'cyber-' were to the halcyon dot-com days of the 1990s).
The new Vacumatics looked quite modern compared to the Duofold; although Parker had updated the Duofold with new colors and a more streamlined appearance, it still had the ball-end washer clip and black ends of the 1921 model.
Since 2004 Parker 51has been published to preserve the rich history and ongoing use of the world’s greatest pen.
