Hi all, I received 4x5 old stock shutter curtain, i wanted one for a 3x4 auto.The seller thought it was for a 3x4 but turns out to be for a 4x5, and was not sure what camera it is for. I kept it for possibly trading for a 3x4 auto or finding a 4x5 needing a new shutter. Does anyone know how to identify what camera a graflex/graphic shutter curtain is from?

Thanks dave
