In October of 1922 this interesting advertisement appears in the Tech. Not for fountain pens but for Ford automobiles.It is not that the automobile is a new technology, but the fact that has now become accessible enough even to "poor" students that makes this advertisement interesting.11-12-1923
In 1924 no Parker pen ads appear. A year later Parker marks its presence with 3 ads. The big red duofolds are still at the same price, while a bandless/small nib D.Q. model is priced at $2.75, while with a larger point and a gold band it is priced at $3.50
From all big four Wahl is my favorite. It started as the Chicago based Wahl Adding Machine Company (a maker of ... adding machines) and in 1915-16 acquired the Eversharp Pencil Company (see more on the early Eversharp history in this link by D. Nashimura). In 1917 they acquire the Boston Fountain Pen Company. This transaction was seminal for the company as soon it changed its name to Wahl Company and sold the adding machine part to Remington Typewriter Co. Pens from late 1910s early 20s bear the name TEMPOINT and they have usually awesome nibs. Ads for Wahl pens appear in the Tech in 1923 and 1924. The early ads were showcasing hard rubber pens but soon the focus shifts to all metal pens - gold filled and silver with prices anywhere from $1 to $10. An interesting data point is the reference of one of the ads to the Wahl Toronto factory.

There are only few ads of Waterman products in this decade in the pages of Tech. They all refer to black hard rubber pens. The locking lever, the spoon deed and the "quality" of the hard rubber are their focal points. These ads are not representative of the range of Waterman pens and their acceptance in the market. This is the decade of the ripple hard rubber in red, olive, blue, etc. This is the decade of the coveted (today) "color" nibs (the famous pink, red, yellow, blue, etc.) Of course much of our "image" of the 20s Waterman pens is formed by our modern collection preferences. Overall, although Waterman products are well established in the market, they are no longer the dominant force of the earlier two decades (1900-1920).
A barrage of Sheaffer ads appears in 1929 in the Tech and is clearly associated with the appearance of the Sheaffer Balance. The 20s were good for Sheaffer. The earlier radite pens, the jade flattops were definitely  and the undesputed marketing success of the lifetime guarantee of the White Dot had placed Sheaffer among the top four manufacturers. The ads here focus on the newly introduced Sheaffer Balance and it is ironic that they coincide chronologically with the stock market crash of October 1929.
The Chilton is a relatively unknown pen brand to most newcomers to the hobby but it is well known and highly coveted among the "elders". It is a pen with interesting history. Seth Chilton Crocker was the president of the Chilton company and he was the son of Seth Sears Crocker of the Crocker Pen company. The Chiltons were pneumatic fillers, where a tube (similar to the much later Sheaffer Touchdown) is pushed down and makes a rubber sac to collapse and subsequently suck ink in when it expands. The company started in Boston during the 20s and then moved to Long Island NY and perhaps in its later stage moved to New Jersey. The Chilton pen ads in the Tech emphasized their large ink capacity. The ads span 3 years from 1927 to 1929. The most interesting ad is the one from 9/26/1928 that shows a leather covered Chilton.You can find many Chilton pen pictures in http://www.chiltonpens.com of Rick Krantz, who has posted 4 of the Chilton ads shown below at L&P on 1/18/06 [ed(az)6/17/06)] . Pens with elephant, ostrich and crocodile skin were among the products of this company.

I am closing the discussion to the 20s ads by presenting first an ad that references another Boston pen company - the Carter's
June, 4, 1929
as well as an unknown to me fountain pen - the Bauer Fountain Ruling pen, and another ad for the Higgings ink.
