Many times when we think about vintage pens we have the false idea that such pens were practically hand made, the product of love of some elderly, wise penmaker. At least, I catch myself to think like this some times. Maybe this is the proper picture for the very early pens, but the pens of the golden age of fountain pens, the Wahls, the Parkers, the Watermans, the Sheaffers, etc. were coming out of fairely sophisticated machines.
I started thinking about this when I read George's post here. I listing here the patents for few of the machines that were used by the Wahl Co. (later Wahl Eversharp) to make some of the pens that we love and enjoy today.
1. US Patent 1395316 "Chasing Machine" by John C. Wahl 11/1/1921.
