There is an old time hobby shop in Grand Prairie, Texas called Wild Bill's Hobby Shop. I was in there recently and he had a brand new never run Cox .15 with the red and blue case. I think that his asking price was $150. I took in an old Sportsman .15 that I got over 50 years ago from some kid back in Jr. High school but he was not interested in purchasing it. I have only had it on a Jr. Flight Streak back in High School. It still has good compression but is probably not worth much since it is in fairly rough condition. It appears that someone, maybe me, tried to take the back plate off with some pliers. I will never use it I know. And none of my G-kids are interested in G-Pa's toy airplanes.
