I have a feeling, ES, it is just a "stock form" with a few details changed!
BTW, in Ocean/BF, we had a small and efficient fuel test kit. It was just to check the bare minimum characteristics but worked. We also had one for LO after microbial contamination became known.
Then there was the Alaska HO, just a smidgeon over 1.0 relative density, the east arabian HO full of sand and the Texas HO full of waxes!!!
Best Rgds.
