I guess the opening line says it all - I'm looking for a source of paraphenylene diamine to make Harveys 777 developer. I'm a UK photographer, but a US source would be fine. Alternatively, a ready mixed source of 777 would do. Many thanks, Neil Miller.
Photographers Formulary carries parephenylene diamine. You can also buy the original formula from Bluegrass in Louisville, Kentucky--phone number 1-502-425-6442.

Ed, have you accually talked with Bluegrass and confirmed that it is the original formula? Curious minds want to know.
hi there i recenlty called bluegrass and asked them about harvey's 777 developer. they said it is the original formula and cost $52 for a case that contains 4 - 1 gallon packages. when i asked what the formula was, they declined and said it was a "secret receipe". i DID find out one thing, there is no glycin in their proprietary mixture. - john
WELL! if it is the original formula and there is NO glycin in it, then that throws a monkeywrench into the whole issue of the formula investigation.
If you know any lichenologists, they'll have some PD laying around. Its used in lichen identification
Thanks for your help. I tried the Photographers Formulary, but they couldn't ship to the UK because this chemical has a hazard rating. I then faxed an order to Rayco yesterday lunchtime and the order was with me this morning - outstanding service! Thanks again, Neil.
