Something smells very fishy here

If Dr Elie Shneour is THE expert on Rodinal (which for all we known he might well be) then surely he would have known & told Troop that the formula in the FDC was actually one published by Andresen & Agfa themselves at the start of the 20th C.

It's rather like the "Authentic" formula for Edwal Super 20, and a few others.
