Thanks Scott. After looking at many many head shots, the closest I've been able to come is Bob Usher, but he doesn't quite look right either. At this point, my brain seems to be telling me every second or third Cub I look at is an obvious match, I think because it is tired and wants me to stop looking at photos
Mark, to answer your question about the first photo, no, I never was able to come up with a positive ID on that one, so back in the "unidentified" pile he went until that "aha" moment finally strikes.
