Good evening all. I got bit by the fountain pen bug a few months ago. To date, I've found two 51s, a 51 special, and a 25 in the wild. All of these are aeromatics. All but one was brought back to live in my kitchen. The other was restored and is my everyday pen. I've also got two very old Underwoods under repair. If, anyone has information on the Underwood Company, I'd be very happy to hear it. All the best, Bob
