TJ's BLEACH

2 g  Potassium Dichromate
2 mL Sulfuric Acid, concentrated, or 4 ml 48%, or 6 g Sodium Bisulfate
30 g Potassium Bromide
One litre water

Bleaching time: One and a half times the time it takes to clear.

Temperature:  20C              Agitation:  Intermittent

The first bleach that I saw that worked with the Agfa HD series of emulsions when they came out, in conjunction with Kodak D-8 as the developer.  It is a bit noisier than current formulations, but just as bright. It is a variation of the Kodak R-10 formula.
