I used to work in a Hobby Shop in Elmhurst, Il. back in the '70s. Dennis and Sue would come in often. They were great customers and Dennis was an outstanding modeler. He scratch-
built a brass HO CB&Q SG 0-8-0 tender for a friend of mine that just had the loco, the original tender went missing somehow.
I also seem to remember him getting some CB&Q engine parts- as they were cutting them up on the scrap line in Aurora, Il. I notice it has an air ringer arm on it, so it may be from one
of those somewhat modern engines that was being scrapped ??
