Most miniature Speed Graphics out there at the moment that people are willing to sell come with the classic spring back that only really works with 2x3 film holders, and no-one mak es that size of sheet film anymore. This conversion allows you to easily remove the spring back by removing 5 scews, and replacing it with a 2x3 Graflex back that allows you to use Mamiya RB or other 2x3 film holders. The four holes on the top of the holder are for M3x4 heat set inserts. Downloadable STEP file included if you need to modify the conversion for your specific camera. You can also modify the step file for CNC manufacturing by setting the diameter of the holes for the screws to attach the wings to 2.5mm and specifying an M3 tap with 4mm depth and 6H thread tolerance.
