Does anyone know what Beseler FD-1 was?

[juan]

I'm in the process of scanning all of my old negatives. I'm back to 1974 when I was shooting Ilford FP-4 and developing it in Beseler FD-1 developer. According to my notes, the developer recommended shooting FP4 at 400. I did some tests and settled on 250, though I really had no idea what I was doing. I think I remember it coming as a liquid in a tube - perhaps two tubes.
I can't find any reference to this developer in any of my books, nor do I see it on line. Anyone know what it was?

Beseler Ultrafin FD-1 was marketed as very fine grain compensating developer. Maybe rebadged Tetenal Ultrafin ?

The Ultrafin is a good guess, but the modern instructions don't say anything about a substantial film speed increase. I'm dubious of the claims, and was at the time, but the instructions certainly showed it. Could be that Ultrafin has changed in 40-years.
I'm also pretty sure there was an FD-2 sold. Maybe that was rebadged Ultrafin and the FD-1 was something else.

Just read in an old review that FD2 was very close to Neofin Red that plus high accutance makes me think that FD1 was Neofin Blau(Blue) or Ultrafin and FD-2 Neofin Rot (red). The one thing I am pretty sure off is that it was made by Tetenal.

Researching further, Crawley's FX-1 and FX-2 describe the same characteristics as FD-1 and FD-2. The similarity of names is also interesting. I think that's probably it.

That is my recollection as well.
