One great example is his latest post where he discusses a short Pilot Capless from 1965. He even compares it with the long version from the same year. I’m not sure if you noticed this but those pens in the image down there ARE STICKERED! Woah.
Once you’re done with that post you should head to his homepage and just start reading everything. A couple of days will probably fly by as do so, but that’s ok because there’s really no better way you could spend your time. If you do happen to drop by, be sure to leave a comment and let Bruno know the ‘Geeks sent ya.
