As I type, these wooden parts are sitting on the side while the black paint and varnish dries. What you see here the body and the back of the Pinholaroid. As well as the 405 pack film back, it should also work with a 545 Polaroid sheet film back or regular 5x4 double dark slide backs. The pinhole front is interchangeable with one of a different focal length, all of which makes for quite a versatile little pin-beast. I can hardly wait to put it all together and try it out!
