The idea of a pen from fifty years ago costing $10 and working perfectly boggles my mind. Here are pictures of the two working ones...


The red pen has the usual drawer wear, but the copper pen is shiny. I think someone polished and re-sac'd it. The red one, amazingly, still has an original sac with "ESTERBROOK" on the side, still flexible.
All I need now is a new sac for the third pen, maybe a different nib or two, and a good excuse not to collect all of the colors and sizes...
