Henri,
congratulations, c'est une optique de six elements tous separe d'air, je m'excuse de mon francais. Pour monter sur une chambre vous pourriez essayer comme suivant:
Achetez sur ebay un Compur Electronic 5 FS, je change en anglais, you may unscrew the two symmetrical front and rear cells, and by means of two adapters simply screw into the very robust shutter, such work can be done by a mechanic and should not cost much. Then by means of a lens board onto which you mount the shutter you will have a well balanced lens which is sitting very balanced without torque (?) on the front standard, and in addition you will lose all the weight of the lens barrel which may be made of brass. I did this with the older 8-element f=16 1000 mm lens. Your lens may be multicoated, these lenses were pretty expensive compared to the standard 4-element artar-type versions and were sold only for the most demanding jobs, a guy from Rodenstock said they were manually assembled on an optical bench . You will certainly need two tripods, and it is nice to experiment with such a monster, a monster also by performance.
Have fun !!
Joerg
