Hello D.C.
My camera techniques/skills are quite limited. The camera I have is an old
Agfa but I used only Kodak film and I really didn't even know Agfa marketed
their film line here in the USA. I don't plan at this point on doing an
experiment , but it would be interesting, I agree. As for running the coil
this winter, I don't think so. Right now I would have to shovel through
about 20" of snow that still hasn't melted that covers my ground point
connection! Just 6-10" of snow in most places around here, I should have
used the snow blower with better planning for coiling activities.
Must be nice in Arizona right now!
Chuck
