kodak rapid process copy film (trial 1)

Today I finally decided to try out one of roll of koda RPC. The person that give me the rolls, told me that he used to make positive b&w, but used his own developer (and lost the recipe and the times).

It's a 0.06 confused iso film and since I couldn't find any info for developing it, besides using kodak dk-50, I deicde do use rodinal. I found an article for the exposures times, from 1987 (the filme was use for copy X-rays). The autors got a conversion table for this film. One uses iso 100 in the light meter, choose the proper aperture to use and them if at iso 100 the time is 1/1000, for rcp film, the exposure must be 2s, and so on!
Since the person who gave me ths film, after some talking about rodinal 1:100/20m, told me that it didn't take so much time for development, so I used the time for agfa 25 ortho: rodinal 1+10, 4m. Fixer right after the developer.
The results

the second one has more post scanning process. Not bad, I think. Now to do some bracketing and to find out the correct developer solution/time, etc.

Thing on trying also Ifosol-3, starting form iso 100 developing time and begin to take minutes!

PS: they come out normal negatives!
