The Typewriter Database News
Imperial page updated Thu, 18 Dec 2014
Imperial page updated with info from OMEF 1980.
Groma Page Updated Thu, 18 Dec 2014
Nick Beland did a quick update to the Groma page, compiling in dates from some new sources. Better dates for Kolibris!
Victor Page Updated Thu, 18 Dec 2014
Richard Polt pointed out research done by Will Davis which puts some dates on Victor machines. His findings were condensed down to a short date table. It's better than nothing, which is what was there before (:
Brother Page Updated Thu, 18 Dec 2014
We've cracked the mysterious "decade code" in Brother serial numbers, which is to say there isn't one. Instead, efforts centered on nailing down what types and models were made in which decade and correcting the slightly wrong OMEF month code error. This page is in a unique format, but should provide clear answers to your dating questions.
Hermes Page Updated Thu, 18 Dec 2014
Added some expanded date ranges for Hermes Electrics.
IBM Page Updated! Thu, 18 Dec 2014
Thanks to the organizational efforts and additional information collected by ProfessorC, the IBM page has been greatly expanded.
Xerox Page added Thu, 18 Dec 2014
I found a PDF of a 1987 Xerox Factbook which indicated the year of introduction for each model made up to that point. Well, it's better than what we had, which was *nothing*. :D
Remington Serial Number Page completely re-written. Thu, 18 Dec 2014
Source #18, the Sheridan Binder, gives us Remington factory production numbers with a granularity of 1-month increments. It took a loooong time, but I've finally typed it all in. Behold, the Mother Of All Serial Number Pages! (:
Hammond and Blickensderfer pages updated! Thu, 18 Dec 2014
Peter Weil submitted his lists of documented serial numbers for Hammonds and Blicks, and so I've added his research as Sources #39 and #40 and added his observed numbers to the relevant pages. Thanks Peter!
Demountable page updated Thu, 18 Dec 2014
I found some new info on Demountable in Source #18, so added that to the Demountable page.
