One last question on the CG, G, G1, G2, GK that all look the same. Do you have any H sockets you can compare to all the various G's. I suspect H sockets are the same G sockets. I have some of both and have inspected them with a magnifying glass, measured their weight, wall thickness, length, and circumference (same size sockets but different series codes) and can't find any real differences. I'm beginning to think that the series codes were orginally developed by Sears simply to hold the manufacturers responsible for the lifetime warrantee. But, as manufacturers got larger and more complicated, the manufacturers themselves added subcodes to identify individual facilities, subsidiaries, production runs, and contracts. So what this could mean is that a company like Danaher, with numerous subsidiaries, and numerous facilities, and long term contracts, could have a huge number of individual series codes so Danaher can internally administer the lifetime warrantees. Is this the brave new world at Sears-Danaher Corp?
