Thanks .
From reading the catalogs, what a great resource here, I think they were made in this pattern from the war to '57 , maybe before the war, too. Gray tools were fairly common in Canada, so it should be possible .Gray are Canadian made. They are double open ends ,engineers wrenches.
I'm missing
#1723 3/8" x 7/16" ,
#1025 1/2" x 9/32" ,
#1027C 9/16" x 11/16",
#1731A 3/4" x 7/8".
My working tools were Gray and Proto from the '80s, both Canadian made.
