FWIW from a long discussion about D76 variants on Ryuji Suzuki's web site, now off line:

"D-76c is a low contrast developer intended for metalographic and spectrographic plates. D-76c contains 0.25g/L potassium bromide and 10mg/L of potassium iodide in addition to straight D-76. One reason for the addition of iodide is said to suppress abrasion marks."

So this is yet another variant.

the one that really works for me is D76h (stable activity over time)

I have to wonder if you are referring to C-76 which is D76 with an additive called Crone C. Back in the 70s when I was in photo school we students were required to use C-76, which supposedly doubled your ASA and gave finer grain. After finishing the Glen Fishback school of photography I never used it again. I never liked the results but if it was still available I might try it again just to see.
