Rollei B&W reversal kit

[Peter308]

I have recently purchase this kit from Maco. The concentrates supplied make 1.2 litres of working solution and the stated processing capacity is 15-20 rolls of film. However, nowhere in the supplied instructions does it indicate what the likely shelf life of the working solution is. I have phoned maco and emailed them twice but they are unable to supply an answer - not impressed. Worst case is I need to process 15 - 20 rolls in one session. Ideally, processing in a few batches over a few weeks / 2 or three months would be more manageable for me.

Has anyone used the kit yet and able to share advice / experience on this point?

Thanks, Peter
