Speed Graphic to Pentax67 lens adapter

Speed Graphic to Pentax67 lens adapter. We’re working on a 6×7 digital back, the smallest size back we would make. The sensor width is 73mm. To fully use that width, especially for video, we’ll make a 4×5 Graflok version. Pentax67 lenses are nice but there is no easy way to mount to their cameras as they have a built in film back. So I’m making some adapters to adapt Pentax67 lenses to a Speed Graphic. We’ll mount to as many 6×7 cameras as possible such as Mamiya RZ67 and others.
