We are accustomed to product reviews, announcements, and launches, and in several generations, collectors of antique smartphones will have ready access to innumerable source materials. For collectors of antique typewriters, finding source materials can be difficult, but in this age of digital archives, less difficult each time a document is posted on the internet.
In 1895, The Phonetic Journal interviewed W. J. Richardson, a London retailer of the Bar-Lock typewriter, that marvelously ornate machine with a double keyboard. This interview is presented here.

Interesting interview. The folks at Olivetti must have read it also as their Margin Release keys also function as a paragraph indentation stop.
I like how the interview is conducted. Interesting improvements, for sure. Remington had a “Billing and Tabulating Attachment” for models 6, 7, and 8, but I don’t know the exact year that was introduced.
I just saw an 1896 Remington 7 equipped with a Gorin tabulator this weekend! I suppose that the tabulator was factory-installed, but it’s just that – a supposition.
