As the unhappy owner of a Durst L1200 with multigraph head I posted a message asking if anyone wanted to swap the multigraph head for a VLS head or Ilford module.
As I expected I heard nothing, nada, bugger all. Then suddenly, quite out of the blue, this charming chap drops me an email offering to swap his VLS head for mine. I nearly choked on my Wallmart pasta bake when I read it.
It gets better. By shear good luck the owner was coming over to the UK and brings the enlarger with him. After a rather warm evening (it was 30 deg C in my darkroom) disassembling and re-assembling our respective enlargers I am now the proud (and very happy) owner of a Laborator L1200 with VLS 500 head.
Michael, many many thanks.
