Hi all, Does anyone know whether there was ever any sort of adapter made to enable a Speed (or Crown) Graphic - or a Busch Pressman - to be used as an enlarger? By "adapter" I mean, a negative holder which would fit in place at the back of the camera, plus a source of illumination behind the negative holder? Even if it could be then used only as a horizontal enlarger rather than vertical, it might serve to enlarge negatives 30 to 100x. Cheers, Ardeshir
