I seem to remember someone told me these wrenches were made by Dannialson. At any rate, they are only marked with the size and controlled steel on one side and forged USA on the other. I picked up the smallest one the other day and now have five, but what is missing? Sizes I have are 3/8-7/16, 1/2-9/16, 19/32-11/16. 5/8-3/4 and 15/16-1. I suspect there may be a 13/16-7/8?
