Retro Rigs | Collins KWM2 or KWM2A

If I could click my steel toed boots three times? I would ask for a Collins KWM2 or KWM2A. One collector noted an item of interest and that is winged emblem (WE) or round emblem (RE). The RE tends to fetch a higher market price. However I have not found a satisfactory answer to why an RE or WE on the rig? Perhaps I'm not searching the Collins Collectors Association using appropriate terms i.e. winged or round. As a teenage ham in the late 70s a few radios stood out and one of them is a Collins KWM2 or KWM2A. I gravitated toward the stories. Let's see if I can find anything on a Drake C-Line? 73 from the shackadelic.
