Hello

I just inherited an old Jobo CPP 4111, I believe it's the first CPP generation, not compatible with lifts and so. But it does have a inversion motor, two motor speeds, temperature control and all sort of that stuff.

It has come with a nice Jobo 4205 drum, that is able to take paper sheets up to 40x50cm.

But my main interest is with film developing. Anyone owning or knowing this unit who is able to tell me which drums are compatible with it?
I mean, should I stick to the old 42xx or 43xx drums (for which I can't really find any legenda) or can I use the modernish 25xx ones?

Thanks a bunch.
