    It says First Rate on the side of the bottles so I figure FR means First Rate corporation
    I cannot find info on those developers. Confuses the hell out of me. They're all FR x-something
    have to find booklets

    If I had such a multitude of chemistry unloaded upon my door step
    I'd perhaps categorize according to it's usage. Of two major divisions
    one might be Ready To Use and a second might be Components. With
    in those major divisions further categorize by function. Dan

    "X-44 is basically a fine grain developer for high and medium speed films.For optimum results,where high resolution is a factor,with thin emulsion films,use FR X-22 One Shot Compensating Developer."
    FR appears to be the manufacturer and X-22 reads like a Beutler type IMO.
    Kodelon is (p-aminophenol oxalate)

    You can substitute p-aminophenol BASE for Kodelon (I've done it successfully).

    Kodak HCA was Sodium Sulfite with a smidgen of Calgon (Sodium Hexametaphosphate) added as a sequestrant.

    Sodium Sulfite is so cheap that I'd recommend using up the HCA (as HCA).

    Hope I'm not bugging people
    Thanks for the responses



    Couple developers I'm wondering if anyone has info on
    I think the dilution of 1:3 with the concentrated "panthermic" flash developer may be of some help in narrowing things down

    SOFTONE i'm just thinking may be a D23/25 metol type

    The 57-D developer. I wonder what that is. High Contrast like a Kodalith maybe? Used back in the 20-40's probably with the rectigraph machines and whatnot
    I didn't buy any of the photo-writ paper that came in long rolls not knowing what it was
    Photo-writ and others is what these machines used in camera to copy with and is listed on the can as one of the paper types this formula was used with

    Rudolph Kingslake commented that Haloid made a great copy paper that may be this Photo-writ that I do not own
