Dear Kal,
I only own the first one by Arca Swiss, and also don´t have a manual for this one. I found that a Mamiya polaback manual helped me, there is no big difference.
But a friend of mine probably can help you:
www.janboettcher.de , click "Jan" on the left side, you will be able to send him an email. He speaks english, and he is the craziest Rollei collector I know. On his site, he only shows the curiosities of his collection, the engineering samples, uniques and so on (and his site is big). He owns almost everything ever produced by Rollei/F&H/whatever. I think he is only missing some pink Bay III lens caps or similar stuff.
Another good place to look/ask for the manual is
rolleiclub.com, I am sure that anyone there can help you.
Regards,
Jan
