Anyone remember Ethol 90?

I once used a can of Ethol 90. Pretty neat stuff, if memory serves. If I recall correctly you could dev a roll of Tri-X in a short time at 90F at an EI of 3200 or 6400. Anyway, I don't see the stuff on the BKA site. Does anyone know if it's still made and if not, do you have a formula?

TIA, Jim
