Red/White/Blue Pocketknives

Shortly after WW I, with patriotism riding high, the major knife companies started to offer selected pocketknives with patriotic red/white/blue celluloid handles. These knives usually have a red, white, and blue flag field, often with an inlaid silver star. Utility/Scout patterns were the most common, but these can be found in many other styles. These were produced through the 1920's, up to the start of the Great Depression.  Remington, Schrade, Imperial, and numerous other companies offered these knives. The picture you see is part of my collection on a period American Flag background. Rather than concentrate on certain patterns or particular brands, I am interested in any early RWB pattern knife. I am always interested in hearing from anyone that has a RWB for sale or trade. I would also just enjoy hearing from other RWB collectors to discuss this field.
