Dear Sirs, Sometime ago (Mar. 1924) we bought from you a 3-pen Chronograph. We are anxious for various reasons to use 5 pens (or 6) on the same width of paper strip. We wonder whether you have any design of small pen which would enable us to obtain what we require with the minimum alterations on the present instrument. Yours faithfully, | ||
