Some orders requested a snap-on part numbers to be modified. Once modified it was able to be restamped with our name. But mostly it was the QT strength testing,nickel and chrome thickness. GSA would send they're inspector out for testing and pull any tools out for testing just to make sure of...
I worked at Granco from 1984 to 1992 as a welder and lathe operator. All the tools were made in Grandview Mo. They were all GSA government orders. I don't think there in business anymore but they were quality made tools. They compared to snap-on.
