Unusual shape, can't make out the name or logo
It is an IHC wrench. I cannot remember the number, but I am sure someone on here will be able to do it.
If the openings are 3/8 & 1/2 it possibly is 1325 E A although most occurrences of that in Gil Irps' I.H.C. book show an "S" wrench in parts lists. 1326 E A is 3/8 x 7/16.
Thank you
