Formula for Tetanol gold toner?

[Fragomeni]

I was just trying to find some Tetenal Gold Toner and it’s coming up as discontinued. Does anyone have a formula to replicate this toner specifically? Or know the difference between it and normal gold chloride?

From recollection, the Tetenal is a fairly standard gold thiocyanate toner. There are Agfa, Ilford and other formulae in the public domain for them.
