Buying and Selling

I am looking to acquire the following items:

Accessories designed for the Franke & Heidecke Rollei 6000 series cameras:

Schneider Super-Angulon 50/2.8 PQS (Preferably AF)
Schneider Tele-Xenar 180/2.8 PQ (Only interested in AF)
Schneider Apo-Symmar 90/4 Makro PQS
7 and 17mm extension tubes


Also looking for the following for the same system but I have very finite price offerings for these (assuming all in mint condition):

Zeiss MakroPlanar 120/4 PQS ($800US)
Zeiss Planar 110/2 PQ ($1200US)
Schneider Super-Angulon 40/3.5 PQ ($2100US)

Bowens Quad system stuff:

Fresnel spot lamp heads/attachments 
Universal spot attachments (or something ellipsoidal and focusable that will mount onto Bowens heads and handle at least 2000W/s pops and 300W modeling power and support steel gobos) 
Bowens Quad system extension cables (I believe that the Calumet extensions don't fit) 
Beauty dish larger than 15" 
Standard 7" grid reflectors and matching barn doors

Other lighting equipment:

Pencil lights (Any vintage, as long as it works and has a working flash tube)
