Swann Pen Auction Sept 2012 Pen Finds.
Chilton was a high quality smaller maker, with pens initially made in Boston, later in Long Island City, NY (iirc). The Wing-Flow nib (and eponymous pen) appeared in the mid 1930's. With the release of plastic pens featuring inlaid metal strips forming patterns and even letters, the Wing Flow series proved popular in retrospect with collectors. Few of them are inexpensive today.
I'll start this thread on the Chiltons I found at Swann with a monster, perhaps the... "king of the series".
So, I offer my key acquisition from the Swann sale, one of just a couple known (risky verbiage, yes, noting I know only of this set and have vague recollection Don Haupt might have one): the gold-filled Chilton Wing Flow
