I stopped by a local thrift shop today and got a book, Fountain Pens-History, Repair, and Current Values by Cliff Lawrence (Collector Books, 1977). The book contains lots of good information, but the last section is a pictured price guide of approximately 100 pens. Naturally, prices from 42 years ago are low, but when adjusted for inflation (314.4%), they show how some pens have far outstripped inflation, while others are about the same (or less) value today. This is not meant as a comment on the accuracy or a criticism of Mr.Lawrence's book. It was one of the first books on the topic, and was written at a time when prices of fountain pens were not well established. Here is a sampling of listed prices and the inflation adjusted amount. 1923 Waterman 58 Red Ripple $105 ($435.09) 1928 Waterman Patrician $65 ($269.34) 1898 Parker 37 Sterling silver snake overlay $250 ($1,035.92) 1923 Parker Big Red $110 ($455.80) 1923 Parker Duofold Jr. pencil in rhr $30 ($124.31) 1928 Parker Sr. Duofold in Mandarin yellow $125 (517.96) 1940 Oversized Vacumatic $30 (124.31) 1946 Parker 51 gray w/gf cap $10 ($41.44) 1932 Sheaffer Balance full size, black $32 ($132.60) 1949 Sheaffer Triumph $10 ($41.44) 1941 Wahl Eversharp Skyline, bandless brown moire pattern $4 (($16.57) 1944 Wahl Eversharp Fifth Avenue fp $12 ($49.72) 1948 Montblanc gold plated cap and barrel (model not listed) $48 ($198.90)
