This is the second shipment in Canada. The first shipment was only 16 units and I bought five of them. Most were sold with in a day or two.
When I re-ordered they went straight to back order but have now arrived. Plus I'm a Walker's camera dealer and email back and forth with Mike a bit. He hopes to add an 8x10 version to the pinhole lineup as well as different "focal length" cones. ( I think that makes sense if you've seen the camera.)
