American Caramel E121 variations questions

[prewinter]

I've been looking at the Cardinals and Browns in the E121 sets, and I'm a little confused on the variations. I've seen lists that include (for the set of 80) a version of the Ferd Schupp card which supposedly spells his name as "Fred", but I've never seen a listing for this card. Does it exist, and if so, is it also present with in the 120 E121 set? Also, I see there are two versions of the Sisler card listed in both sets, but I've never seen the "Throwing version" with the E121 120 card back. And finally, I've seen one version of the E121 set of 80 Hornsby, with the position as 2nd B., but I thought I saw a posting here from many years back identifying one of these with the 120 card back. Is that correct? So far I've only seen 2B and O.F. with the 120 card back.

Thanks for any help. I've skimmed through this forum before, and it seems there is a lot of interesting details and helpful people here.
