Just picked this one up, and owe note of thanks to Pearce Jarvis for pointing me in its direction. 2nd Generation Wahl Doric, mid-late 1930's, vaunted blue shell with white trim. Largest size. This one is not perfect (how many are?) with need for a better nib and possible (i have yet to loupe it) single ridge of barrel threads mushed/stripped with absolutely no impact on cap closure. But... grand color without crazing or fluorescence. Sharp imprint. Superb trim. A not-so-easy-to-find Doric by any stretch. It shoots up nicely too ;) http://vacumania.com/penteech/wahldoricblueshell850a.jpg regards David
