There is additionally a package containing 2 bottles, labelled Metol-Quinol Developer.
The desensitizer is probably ferrous oxalate. It allows you to develop under brighter light by inspection, but does not totally desensitize (i.e. fix) silver.
Chromium intensifier is typically based on potassium dichromate.
Sepia toning bleach is based on potassium ferricyanide.
Green toner is typically based on ferric ammonium citrate.
The glaze used prior to world war two was a protein complex made from bile harvested from cattle (seriously!).
The metol-quinol developer might be similar to D76. Metol was discovered as a developing agent in 1891, and quinones had been known as developers since the very early days of negative-positive processes. Metol and quinones are synergistic developers, with the metol developing and regenerating the quinones.
Anything that can oxidise probably will have done so over 90+ years. The chemicals would be vastly more valuable and useful as historical artifacts than as chemistry.
