Today I picked up a small 3" monkey wrench, with a screwdriver tip. The logo on the upper jaw is inscribed in a rhombus and reads: -A- G & J PRODUCT. The only G & J I have seen on wrenches before this one were made for Gormully & Jeffery for their Rambler bicycles, motorcycles, and brass cars.
Can anyone tell me if this wrench was made for, or perhaps by, Gormully & Jeffery?
