great article Scot! extremely informative.

i hope you don't mind, but i wanted to mention, it seems like you have missed some recent sales for the ultra rare backs. there were something like 5-6 BL 460's that sold recently. (which as we all know is extremely rare to occur all at once). about 4 on ebay, one in Heritage, one in Goodwin (i believe), all sold since that one sale you referenced in January. same goes for Drum. i think there were multiple recent sales (REA, Goodwin, Heritage). i only say this, thinking this could further inform your data in that area.

Best-

p.s. if you are unaware of these sales, i'd be more then willing to help you research those sales numbers. shoot me a PM.
