Dwight,
Try ebay for an old argus model a....or check flea markets for old folding
cameras with small shuttered lenses...some model shutters have lots of timed
speeds, some don't so you'll have to look. When you find a good one remove
the lens/shutter assembly, remove the lens cells, set the diaphram to a
medium aperture and tape your zone plate directly to the diaphram. If you
tape the zone plate very well, the diaphram blades are quite secure, but it
does help to pin the diaphram adjustment lever in some way.

Here's my zone plate argus....

I discarded the lens cells but used the barrel as a hood for added protection
to the mechanism. I adapted prontor II shutter to the camera too...this
shutter has many more speeds than the original argus item. Good luck

Mike
