Can anyone ID these 3 cards? Vintage

[Yanks21]

I am working on a project and I am hunting for these players that once played for the Yankees. I am collecting these cards from a poster I have of players that played in a Yankees Old timers day. Some of the cards show them in different uniforms so I do not recognize them. Some of the cards are originals but there are oddballs as well. If you can tell me what any of these cards are that would be a great help. Thanks, Kevin in CT.

First pic looks like a 1940 Play Ball to me. Third pic looks kind of like a Conlon card.

40 PB, 39 PB and not quite sure on the last one.

Thanks guys. I figured out the middle one with your clues:
1939 Play Ball #122 George McQuinn

Bottom card is Rollie Hemsley. St. Louis Browns catcher from 1933-1937. Played part of 1933 with the Reds, played for the Yankees from 1942-1944. The card itself is a 1936 Goudey (unless it's a reprint of course!)

Here's your card on Ebay right now:
