1) The "F" and "M" are to match the shutter timing to the peak output of flashbulbs. "F" bulbs peak 5 milliseconds after ignition, while "M" bulbs peak at 20 milliseconds. Each is of a relatively short duration, but not as short as electronic flash. "FP" (focal plane)bulbs are a horse of another color as they peak after about 5ms, but have a long duration so a focal plane shutter can be used at higher speeds.
3) This looks like it takes a standard 9V battery. I don't know of any other batteries that match the terminal configuration of the 9V. -P Lasse Karlsson wrote: > > > 1) Regarding the Zeiss Ikon Nettar "front piece": You can see this red > little thingy set at "F". > Now what does this red thing do there?
