kapro and paul ewins:
Your answer is LIGTHTWAVE.
About four months ago I needed a DeVere adapter for an ILFORD 500H and they made it for me. I’m sure they will solve your problem, since they asked me if I needed light boxes (I had a Beseler adapter, but the DeVere was mising).
You shoul visit:
http://www.lightwaveservicing.co.uk/New.htm. An excellent service: fast, affordable, accurate... I had a great experience. Tony was the man who solved my problem.
Anyway, if you (kapro) need it I could take a look at my own ones and measure them for you.
I hope this is of any help, as it was for me. Good luck.
Marcos.
