A. A. Waterman's sacs were guaranteed for only two years, replacement cost 25 cents (p. 349).
The Sterling Fountain Pen Company originated in the February 1899 dissolution of A. A. Waterman & Company and its takeover by Rhodes Lockwood, formerly a silent partner and the firm's financial backer (pp. 185-86).
A December 2, 1909 letter from the Modern Pen Company states, "Within the last year Mr. [Arthur A.] Waterman was withdrawn from the Chicago Company and is now with the Held Pen Co. of Salt Lake City, Utah" (p. 592, see also p. 595).
In December 1907, Waterman bought 1512 gold nibs from the Modern Pen Company for $393, including a $15 charge for "Altering tools" -- presumably, the tooling charge for the imprint stamp (pp. 547-48). The transaction was indirect, the nibs being sold by Modern to William L. Chapman and by him to William I. Ferris (pp. 118, 126). According to Chapman, he dealt directly with company president Frank D. Waterman (mistakenly called "Fred") and Ferris, and set up the transaction at their request to conceal that they were buying nibs from a rival (pp. 146-48). Ferris later claimed that the nibs were bought for Aikin Lambert, but court adjourned for the weekend before he could be pressed on this, and when the trial resumed the following Monday, the questioning moved in other directions (p. 191).
According to Walter L. Rieman, in charge of Waterman's repair department, 350-400 packages arrived by mail per day, some with more than one pen. This impressive repair volume did not include repairs received over the counter, as there was a separate repair department attached to the retail department (p. 406).
