A few weeks ago I bought an Esterbrook Dollar Pen that was in fairly decent condition even though it didn't work. The barrel, section, lever, and feed were in good shape but the nib was used to spear cheese cubes or something. It was crumpled and not repairable, so a new nib was in order. To add insult to injury, I put some gouges in the section when my re-worked pliers slipped, including a very noticeable nick at the lip of the barrel.
Over at Fountain Pen Network I met 777, who repairs Esties. He's restored the pen, including working out most of the scratch marks and gouges, and sent me these pics. I can't wait to actually see it and give it a try (before it goes on to someone else), the blue is really beautiful.
