According to The Jewish Transcript, a Seattle paper dated June 23, 1933, Warshal was:
"the first Jew to be on the national junior championship team of the United States Revolver Association."According to The Jewish Floridian paper, dated October 25, 1935, then:
"rank[ed] as the nation's number one Jewish marksman, having won the national championship for picket revolver shooting at the U.S. Revolver Association's meet."
I didn't find much else. Anyone with information please feel free to comment.
