Hey....

I think you are missing the mask, if that's all you have. You'll just have to be aware, what you see on your view finder isn't what you are going to get on your film. (because film is smaller) I think you did get a pretty decent deals.... You got a lot for $500. I think once you get 6x7 back, you may begin to appreciate the size of the negative.... with 645 back, you really aren't using your camera to its full potential.
