Default Gas Cylinder ID

Both of these gas cylinders will pass 7 of the 8 tests in Wayne Bradford's 8 step IHC gas cylinder test. The stacking swivel screw on the top cylinder has questionable IHC staking and bottom cylinder has a K stamped on the bayonet lug. The bottom cylinder has been refinished whereas the top one has not. It's hard to see in the pics but both stacking swivel screws have concentric circles on the screw head which passes that part of Wayne's test. Any help on a positive ID on either or both gas cylinders is appreciated.

FWIW I think the top cylinder is IHC and the bottom is not.

Concentric rings alone mean nothing as SA can also have them . IMO bottom cylinder is SA. I cant say for sure abut the top one
