    KBT and T-8 are not quite the same. KBT is concentrated 
and is diluted about 1:30 for use, T-8 is used full 
strength.
    Some time ago a posted a couple of formulas for 
combining KBT and KRST. One formula was from a Kodak 
publication, the other from a magazine article, the latter 
appeared to be the actual Polytoner formula. However, Ryuji 
Suzuki tried at least one of these and found that it caused 
immediate and deep staining of the prints treated in it. 
Presumably, the formula for one or both of the commercial 
products had been changed since the formulas for combining 
them were published c.1955. At the time Polytoner was not 
yet available. I will repost the formulas if anyone is 
interested but won't here since they evidently don't work 
anymore.
