I figure one way to get more responses is to present multiple seemingly unrelated questions

First, did anyone here bid on the domino disks set broken and sold by davidbvintage last night? There were some real nice ones there, although PSA grades them inconsistently. I won this Moran Cubs disk, one of the seven players with variations.

One guy won a boatload of these, and I noticed that when I looked at the winning bidder, his scrambled name was always different from one auction to the next, even though they just ended minutes apart. I get the scrambling part in general, but has Ebay been doing this immediate differentiation for awhile? I hadn’t noticed and don’t really care, but wondered why the same high feedback number was tagged to so many different bidder “names” for what was obviously the same person.
Also, I won the Scanlon Phillies disk, another of the variations, and noticed in my research that Baseball Reference and several other sources call him Scanlan. His faux signature on T205 is ambiguous and the card back calls him Scanlan (so too T202). But when I searched him in Sporting Life under Scanlon I got plenty of hits (didn’t try “Scanlan”), and both T207 and the p2 pins use Scanlon. Anyone here know which is correct? I’m leaning toward Scanlon, since the Sporting Life had beat writers and I would think they would not regularly get it wrong.
Finally, just a general call for info on the Px7 disks–feel free to show them if you got ‘em. FWIW, the Moran disk has always vexed me. I am convinced it is the main or only reason any guide has attributed the set to having originated in 1909, the theory being that Moran played for Chicago in 1909 and Philadelphia in 1910. However, he started 1910 with the Cubs and rode the pine for the first few games of the season, joining Philly in May, so the disks could have been and in my view were produced after 1909.
