After I have got the bad news that Paterson is not producing chemicals
anymore I have wrote email directly to them. Today I have received answer.
The answer is actually kind of optimistic. Please read for yourself.
Quoting Roger Parry from patersonphotographic.co.uk::
The situation is that our sub contractor who mixed our formulations as
closed its UK plant leaving us without a chemistry producer. We are
trying to find a replacement contractor who can manufacture the
chemistry a reasonable cost. So although we are currently in a no stock
situation there is a possibility that we may be able to re-introduce.
we are making efforts to rectify the situation but that there is no firm
news at this point in time.
