Saw this one in an antique store last week and went back 2 days ago and bought it cause it was so different. First thing that caught my eye is it's size, about 19 inches. Then what is usually the flat smooth area around the openings reminds me of a crescent moon on this one because of the shape. I quickly realized it was pre 1929 due to the sizes marked for the openings, 3/4 and 7/8, which actually measure 1 3/8 and 1 1/2 which are marked 32 & 38 on the other side. Then in about the center of the side marked 32&38 is a triangle with an S inside. Did some searching on various sites for who might have used the triangle S as their logo/trademark but found nothing. Can anyone out there tell me more about this wrench, maker, approximate age, what it was used on/for? TIA for any help you can provide.
