Official Checklist HERE
All of the players that could be easily identified by their listing in the checklist have been linked. Now all that's left is to figure the oddballs.
There are numerous misspellings in the official checklist, ex. Lawrence Bearnarth is spelled Bearharth in the checklist as well as on the card's slab itself. So the remaining ones could be so misspelled they cannot be pinned down to one player.
Names that need verification and potentially fixing:
Albert Elliot - "Elliot" is definitely misspelled (All of the Elliotts were misspelled Elliot in the checklist), but even then no Albert Elliott has ever made it to the bigs. Could it be Allen Elliott (1897-1979) or Bob Allen (birthname Alvah Elliott, 1894-1975)?
Bill Keely - Bob Keely (birthname Robert William Keely, 1909-2001)? Or could it be a misspelled Kelly and be Bill Kelly (1898-1990) or less likely Billy Kelly (1886-1940).
Hal Smith - Common mix up. Is it Hal W. (1930-2020) or Hal R. (1931-2014)? But I guess there is a chance it's Hal L. (1902-1992).
Herb Hudson - Closest is a Hal Hudson (1927-2016).
Hiro Andrews - Closest is Hub Andrews (1922-2012)
Jeff Barclay - Only two Barclay's ever made the majors. One is Curt (1931-1985) and the other died in 1909. Jeff Barkley is already in the checklist, could this be a misspelled duplicate? Maybe HA misspelled a few Jeff Barkley slabs and it ended up in their list.
Jerry Morton - Couldn't find a Jerry or a Gary, or even a Gerry or a Jary.
Jim Adcock - Only player it really could be is Joe Adcock (1927-1999), but how could it end up being "Jim"?
Jim Batchedler - Only player named Batchelder in the majors is Joe Batchelder (1898-1989), and he's already in the checklist. Maybe another misspelled dup from HA, and another Joe to Jim mishap at that.
Logan Earley - Logan Easley (1961-)?
Max Person - No one close.
Mike McGann - Only 2 players named McGann ever played in the majors, none after 1908. No idea.
Pat Kennedy - ???
Ray James - Nadda
Rick Bleat - Not a single MLB player with the name Bleat.
Sandy Armas - Sandy Amoros (1930-1992)?
Scott Fitzmaurice - Gotta be Shaun Fitzmaurice (1942-) right?
Stanley Klapp - Not a single MLB player with the name Klapp.
Todd Davis - A lot of Davis's out there, but I don't see a Todd. The checklist even spelled it "todd".
Tom Detore - The only MLB Detore is named George Francis (1906-1991), who is already in the checklist.
William Moore - William Wilcy Moore (1897-1963), William Austin Moore (1905-1972), William Ross Moore (1960-), William Allen Moore (1892-1964), William Henry Moore (1901-1972), or William Christopher Moore (1902-1984)? Boy, what a generic name.
