This collecting thing never ends!!! I now have/had (minus one) 4 variations of the front cover Princess name displayed 100-A reel. The first is with the Princess name simply stamped on the front cover. The second variation is when Johnson started painting the name on the front cover rather than stamping. And the original painted variation letter size was the same as the original stamped letter size. It is the middle reel in the first pic. I sold it since it appeared someone had taken the front cover and side plates and put them on a regular Century. But it does show the second variation front cover. Then Johnson next increased the size of the painted letters keeping the location pretty much in the same location as the previous stamped and small painted letter variations. Finally I think the last variation was moving the painted name to fit between the slots as shown in the 2nd pic, right reel. Until I find another variation, I think they then moved to the 100AP and finally the 100BP. Another quirk I think is while I know the papers that came with a 100AP identified it as such and I assume the same with the 100BP (although I don't have 100BP papers), I have never seen a Princess box with a model number on it other than "100-A". Don't know if they ever made a 100AP or 100BP designated box.
