I once bought this toner from Photographer's Formulary.
This toner consists of Stock Solution A and B. To prepare part A
you have to prepare solution 1 and 2 first than mix them together
to get part A:
<bold>Solution 1
</bold>				<bold><italic>	1 Liter	2 Liter	4 Liter
</italic></bold>water 125°F				750ml		1500ml		3000ml
sodium thiosulfate, anhydrous	152gr		305gr		611gr
potassium persulfate			 30gr		60gr		120gr
water to make 			1000ml		2000ml		4000ml
<bold>Solution 2
</bold>
water 68°F				  16ml		32ml		64ml
silver nitrate			  1.3gr	2.6gr		5.2gr
sodium chloride			  1.3gr	2.6gr	5.2gr
<bold>Combining Solutions 1 and 2 to get Stock Solution A
</bold>
Both solutions must be at 68°F. Stir solution 2 vigorously to disperse
the solid 
throughout the solution, than pour all of Solution 2 into Solution 1. Mix
thoroughly.
<bold>Stock Solution B
</bold>
water 68°F				62.5ml		125ml		250ml
gold chloride				0.25gr		0.5gr		1.0gr	
<bold>Mixing the Working Solution
</bold>
To prepare the working solution one-half of Stock Solution B is added to
Stock
Solution A, the rest of part B is used as a replenisher
<bold>Replenishment
</bold>
About 4ml of Solution B should be added to the working solution after
fifty 8-by-10 prints
have toned. Exact measurements cannot be given
