Frank,

That's exactly what I needed to know. Will have some time to dig 
around in the darkroom starting from next week. Have taken the big 
leap into the unknown and will be without a regular paycheque from 
tomorrow!

Will let you know what I find in the cupboards :-)

Thanks for the tips on the anti-halation backing wash cycles. Will 
have to take a look at the SilverPrint catalogue to see if there is a 
Rollo Pyro brew available. I am a little reluctant to try making my 
own after all the warnings about mixing up from powder form.

Cheers,
        Clive
