The print on my website is a gum print of
Demachy's.
Here is a URL for powdered pigment, Indian Red, and
Sennelier red ochre.

Chris,
I think you are right. If I remember,
the Red Chalk or Sanguine was a special chalk that had a lot of iron oxide in
it.
Were the Demachy prints in this color gums
or photogravures?

Henry,
Try Venetian red, Indian red, or red
ochre. It was a red iron oxide pigment if I remember correctly. One
recipe calls for 3 g. Venetian red powder to 1/2 oz. gum. Another calls for
a pigment called "light red" which I know was available about 10 yr ago
anyway. But Venetian Red is a nice brick-y color that you'd be happy
with. My notes say this: "For
instance, a Venetian red or red ochre color was used to approximate
the rust colored conte crayon
portraits."
