Can we come back on topic.

My contact with Dr Dr Shneour was to try and find out more about Rodinal, and to hopefully tie up what I've found in 1930's Agfa Patents relating to additives to a p-Aminophenol developers and the mystery additive mentioned in the FIAT reports.

None of this information has been published in any books or articles, and I had hoped that Dr Shneour might have been able to shed some further light on this in view of any analysis he's done of Rodinal.
