I picked these 2 wrenches up at a yard sale.What do you think they are for ? The small one is marked " 9 W " and has a small tit on the end that measures just under .300" dia. and .210" long. the whole wrench is 4 13/16 " long. It's a 9/16 x 11/16.The other wrench is marked "25" on one side and "SC" on the other. It measures 6 1/2" long.this one is 3/4 x 15/16.the square is 5/8.I was thinking farm wrench.Any ideas ?
