Hello All:I recently was given what appears to be a 9x12 cm plate camera.The only problem there is no definitive manufacturer markings.What markings I did find are as follows:Lens is a 6.8 130mm CP Goertz DOPP anastigmat syntor,Speeds T,B,1,2,5 10,25,50 100.F-Stops 6.8,9,12.5,18,25,36.Camera is similar in design to a Zeiss Maximar 207/7.

Any information on this camera would be greatly appreciated.
