For a long time one "Orthodoxy" was that the Centurion Ironman expert was the same frame as the Centurion Ironman Master. It was repeated over and over. However we now know they differ in several ways. Just someone saying they were different wouldn't cut it if someone held in as high regard as Tmar had said they were the same frame. However, we now know they are different because it's actually physically visible.
Hummer was questioning Tmar stellar work on Centurion serial numbers. Tmar having laid the ground work, Hummer thought/thinks the serial numbers dates are off a bit. His version varies ONLY slightly (as it piggybacks off of Tmar serial number deciphetring) and is the one I use.
Which is worse? Having expectations of someone, comparing yourself to others, or having a big ego? These questions have nothing to do with this thread, but hey, it's 2020 .
