Rollei SL66SE Exclusive Pro--How to operate?

[josburke]

I'm new here and seek advice--I just acquired a Rollei SL66SE that is marked as a Exclusive Professional and numbered 92 of 144--25 th anninversary model I think---I have no idea how it works--I'm a Hassy user and a RolleiFlex TLR user as well. The camera was purchased from an individual that knows nothing about the camera other than it was bought by his (late) Father as a collectors item. It has a roll of film in it But has never been fired the first time since leaving the factory--It is unused (no boxes or paperwork--lost after his demise)--please advise how this thing works----is it worth anything as a collectors item? I bought it sight unseen along with a 3,5 Planar 12/24 TLR --
I put a fresh 6 V battery in it but what is the little switch just ahead of the crank on the right side---is there an "ON" button for the metering or ????
Please advise by pm or email.
Thanks
