Hello, just my (possible) 2 cents, or whatever...
Back in 1980s in Moscow we used the following formula in our camera club. It was known as FGF, but people in the club who had access to foreign literature on photography said it was identical to Microphen:

Water (T 50 C)      750 ml
Sodium Sulfite         100 g
Hydroquinone         5 g
Borax (crystalline)   3 g
Boric Acid              3.5 g
Potassium Bromide (10%) 10 ml
Phenidone               0.2 g
Cold water to make 1 l.

I cannot guarantee that the above is indeed Microphen, but whenever I hear the name this is the formula I think of.
Who knows, it might help?

Cheers,
Fyodor.

This is the exact formula in The Film Developing Cookbook that the authors call Ilford Replenishing Developer. There are also two different replenishment formulas, one for topping up and one for bleed replenishment.
