1950s 1960s Pickett N902-ES Simplex Trig Slide Rule Slipstick w/ Orig Case & Box:

Pickett N902-ES 10\" Simplex Trig All Metal Slide Rule or Slip Stick with Original Case and Box, in Excellent Working Condition

This high-quality, carefully crafted, vintage slide rule - from 1959-1962 (see notes below), when they still made things \"the way they used to\" - is in wonderful shape and will help you work out your trig problems just as smoothly today as it did for some unsung engineer back in the early \'60s.

Everything is straight and true (no bends, dings or kinks), all the pieces are intact (no cracks, chips or missing chunks), and all the figures and inscriptions are deep black, bold and easily legible (no rubs, fading or scratches). The original leather/ette soft case and delightfully vintage box (with superb graphics and typography from that era) will help you to keep it in this outstanding condition, as they surely have for the last 60+ years.

The box shows evidence of service in these duties, and has the wear and tear we expect to find on an actively used cardboard storage box from so long ago.

The rule itself wears only one set of modifications, which could be seen as a blemish or an added value / enhancement to the historical interest of the piece, depending on one\'s viewpoint: It has the acronyms \"USP\" and \"UTC\" (or possibly \"VSP\" and \"VTC\") etched into the front of the upper and lower stock - once each on each end - and \"USP\" / \"VSP\" once on the slide, next to the logo, for a total of five tiny etchings. These are visible in the photos here, which I encourage you to study. More notes on the possible origins of these abbreviations are below.

Again, please make sure you\'re familiar with all descriptions and photos I\'ve provided here. As I don\'t take returns on unique vintage items whose condition dictates their value, I want you to have a complete understanding of what you\'re buying, because I want you to be thrilled with what you receive. Thank you!

Notes on Dating and the Production Year

I\'ve done the research and narrowed down the specific vintage of this classic slide rule: between 1958 and 1962. The logo alone reveals that much. Further details - in the construction, materials and styles of the stock, slide, stator posts, bars, cursor bars, tension springs, and lens - are consistent with this short period of years and confirm the conclusion. Unfortunately, they don\'t help to narrow it down much further, but I believe we can rule out (no pun intended) 1958, for a three year window of 1959 to 1962.

That\'s pretty narrow, but if you\'d like to know more and get an even better idea, I can tell you that there\'s a surprising amount of information on the web about slide rules, and Pickett rules in particular... and that it\'s fun to explore!

Notes on Inscriptions \"UTC\" and \"USP\"

What do these trios of letters stand for? Curiosity, coupled with my desire to offer a historic piece along with its potential history, sent me digging for answers.

Experience tells me these letters almost certainly indicate government origins, with private industry roots as a secondary possibility (several factors, including the presence of two sets of letters in the same hand, signify that these are not an individual\'s initials).

It was immediately obvious that the likelihood of either of those first letters being a \"V\" is very low. There just aren\'t a lot of viable candidates with those initials. (There are candidates, such as the Virginia State Police, for whom a slide rule being in their gear collection just doesn\'t make a lot of sense). One exception to this would be a Visiting Scientist Program at a local university or think tank - such as the web-suggested Utah Technical College.

I\'ve acquired other old tools and instruments stamped or engraved or embossed with \"US WPA,\" \"CCC,\" \"USMC,\" \"USFS,\" \"BLM,\" and other known acronyms from storied government entities. The \"U\" in our two mystery monograms would almost certainly indicate \"United,\" \"University\" or \"Utility/ies,\" yet as this slide rule was part of a Utah estate, another whole set of possibilities becomes equally likely...

And so on and so forth... and after following this train of thought a bit further, I realized I was spending too much time on it, and going deeper and deeper into the realm of obsession. I pried myself away and accepted that this is a future owner\'s case to crack, or no one\'s - but no longer mine.

While I didn\'t solve the mystery, I did make it far enough to pull the most likely candidates for the two acronyms (from the surface internet\'s limited resources). That likelihood is based on the nature of the tool, as well as its derivation. For the inquisitive, I leave those filtered results:


United Technologies Corporation / Company

Utah Technical College

Utilities and Transportation Commission

Utilities Telecommunication Council

Utah Technology Council / Commission - I\'m fairly certain this did not exist until this century and can thus be eliminated.


United Steel Products

United States Patent

Urban Services Plan

University of the Sciences in Philadelphia

United Surgical Partners International

United States Penitentiary

Utah State Prison

If you have any information or know the answer to this puzzle, I\'d love to hear from you. Thanks!
