To Salem: You are correct, Sinar is a rail camera.The pictures are from Linhoff, Mamiya C330 and Mamiya RZ67 and RB67. I do not have a picture of the full Sinar set at the moment.
To AgX: I am sorry if I was too forward with my first post in Apug. To be honest I do not have the slightest idea of the whole analog camera, so I need all the help I can get, since I do not know if the cameras I own are worth selling to more professional hands or I should keep them. Also , I am not advertising or selling at the moment, just trying to show the condition of those cameras.
Thank you in any case and I promise to move this discussion to a classified section.
