nice to have you here!
i have to admit, i am a collector and tinkerer as well.
i used to buy falling plate cameras like the cyclone sr. - ( you load all the glass plates in metal septums inside the camera, make the exposure & wiggle a knob - the exposed plate falls to the bottom of the camera & you are ready to make your next exposure ). i'd fix the shutters, uses them for while and then re-sell them on FEEbay sewing machine oil does wonders with a guillotine shutter <g>.
ps. thanks for the links!
