"Do you notice any improvement in the writing done with the 'Biro' pen? Jim tells me that he will never want to use any other kind. It was invented during the war for the use of the RAF pilots whose pens failed to work sometimes at the high altitudes."
Herbert Brush, Monday 2nd June 1947.
"I went to the British Museum and bought a 'Biro' pen on the way, after going into three shops where the pen was sold out as soon as they obtained a supply. I have heard so many good accounts of it that I made up my mind to buy one and use it in my diary. The pen runs well and seems to suit my style of writing, and goes very smoothly, no matter how hard I press."
Herbert Brush, Tuesday 15th July 1947.
