That would be Ib, IB, IIc/C, IIIc/C.
I used it on a IB with very good results.
They made different sets for 45 mm lnese and 50 mm lenses the difference was the number of close up lenses. For the one category they issued lens I and II was enough you had to use both for the closest distance wheeras for The other they added a lens III....just forgot which combination was for which lens.
