@Richard: Would you be so kind and check your source for the birth details you give for Al Putnam (06 May 1910 Tulare, California)?
MotorsportMemorial & ChampCarStats say that his full name was Adelbert William Putnam and he was born in 1907 or 1908 in Salt Lake City, Utah.
FindAGrave shows a tombstone
with the inscription Putnam Adelbert “Al” 1908 1946.
And I found two sources – this and that – which let me believe that Al Putnam was in fact born in Salt Lake City on 09 October 1908. (You find this specific date in the first link - it needs a bit of scrolling.)
