The original box is molded with an oval mound circling the pen to hold a small faux pearl necklace missing. An uncommon demonstrator, seen much less often than 51 or Snorkel demonstrators. Also the barrel threads were extended raised. Robert Goepfert was in the Technical Division about five years. Red band desk pens are more common than pocket pens. It is completely devoid of any markings. The pen was stylish but not flashy, durable but not clunky, and reliable but not overengineered.
The Model Shop employees wore heavy work aprons with pockets for micrometers. Later production again returned to a brass base. Most likely this was due to the pre-war constraints on strategic materials. But there are almost always traces to indicate that it was there. He currently is Senior Principal Researcher.
This pen has dish-style tassies. Aerometric 51s used a transparent synthetic sac that is extremely durable but prone to darkening new replacements are available. This process was eventually put in production to replace gold metal electroplating after I left Parker. Frank also worked on the Liquid lead pencil and helped with many of the fountain pen designs. Parker also manufactured 51s in Canada and England, and later in Argentina. A I am confused as to what model it is exactly.
The replicas do not so far carry any date code imprints. It was an interesting project. In 1955, a matching 51 Jotter ballpoint was introduced, along with the so-called Liquid Lead pencil -- a nonretractable ballpoint using a graphite slurry. In the first years, 1948-1949, the filler was fully covered as in the full size version. Matching date code on nib. It took an eight exposure 16mm film cartridge.
I joined him there in 1983. One somewhat boring task I did was put a tiny mark on the inside of two shells at a time with hot needles. Forest Beck was also there over 30 years and received one patent. Condition is also very important. From the top: India Black, Cordovan Brown aka Burgundy , Dove Grey, Cedar Blue, Nassau Green aka Sage , Mustard aka Yellowstone and Tan aka Buckskin Beige. Parker made a rollerball section, a felt-tip section, and a ballpoint adapter.
Some of these designs are very rare. Some collectors speculate that the ones without a datecode are really pre-production models from 1940. And that logo once again. Some of the technologies which will be covered in more detail later were plastic injection molding, plastic extrusion of writing tips, screen-printing, powdered metal fabrication, powdered plastic coating, and sputtering.

First quarter, 1952 This single digit code persisted until the end of the 1940s, when a second digit appeared. He was at Parker over 30 years and was head of Product Engineering for over 15 years. All engineering specifications were officially transferred to production mostly by Larry Pierce. It also, in my humble opinion, is one of the nicest pen designs ever made. Included in the procedures were practices such as Sample Numbering. These were presented to the Company management in 1967.
All experiments, tests and procedures were written, signed and dated in the notebook every day. Our talented teams of craftsmen and pen experts work together to create ranges of new, hybrid, sophisticated writing instruments, crafted to delight you for years to come. Examples have been found in black, gray, navy blue, teal, burgundy and forest green. I suspect that the real problem may have been high assembly costs due to the lack of any internal provision for automatically aligning the nib and feed with the shell, such as was present in the 61. It was, though, not entirely like those old caps, as there was a clutch mechanism inside which acted to grab the body of the pen very positively and prevent the main part of the pen from dropping into the pocket. The first technical person hired by Kenneth Parker was Galen Sayler, Chief Chemist who received 6 patents. Jerry Kelly left Parker and used his ink expertise at the Wisconsin State Crime Laboratory.
Much of the outdoor furniture has this type coating now days. Clip doesn't quite touch barrel. My website is a compilation of my findings. Bob Burkhalter flew to Germany to procure a dye. Before Snub the supervisors were Bob Rudin, Sam Helgeson and Jerry Flynn. If You feel that Your copyright has been violated please contact the. The following is copyrighted © 2007 by David R.
I remember him telling me about sifting the dirt in his front lawn to remove the stones. With a microscope Frank enlarged the textured ball surface; counted the grains and determined the percent of porosity. The button plunger is non-functional - glued in place to maintain the original look. Feel free to through to help this site to stay online. Rather than abandon the newly-launched flagship pen, Parker made some changes to the filler to reduce its reliance of vital metals aluminum, mainly and made a patriotic advertising point out of limited availablity. Interestingly, some of the 1942 production pens are found with aluminum speedline fillers. The first date codes came in two digits, where the first digit denoted the quarter and the second the year.
