I picked up this beautiful brown and green Inkograph for $15 in a local Antique Mall yesterday, and I can't for the life of me figure out what model it is or what year-range it may have been manufactured in (mid 40s to early 50s maybe?).
This pen looks almost exactly like their Ink-D-Cator line, except that my pen is way more tapered at the ends of the barrel and cap. Also, the clip reads INK O GRAPH instead of INK D CATOR.
Does anyone know what model this is and when they manufactured them? Thanks!
