Karl,

Thanks for the suggestions - the lens is unmounted and looks as 
though it has never been used. It will probably get used for 5x7 but 
is an unknown quantity at the moment. I have been able to find out 
very little about it - would really be interested in any feedback 
from someone who has used a similar lens.

Thought you were rather keen on using that 360mm Tele-Xenar for 
portraiture.  Looking for something longer now?

There is a 15" Tele-Optar already in the kit bag for making 
portraiture focusing difficult - nothing that a bit of rope and a 
head board won't cure ;-)

Cheers,
