Hi all, I´ve just acquired a Siemens 2000 16 mm sound projector in good working order. There´s only one part missing on it, the release knob for the lower sprocket wheel. It can be handled by manually pulling out the knob axis (with a pair of pliers) but it would be good if I could just find a suitable knob. The knob is springloaded and threaded on the axis so I was thinking of temporarily putting on an ordinary nut or locknut on the knob axis, but when I try with a M3 nut it will not fit. Could it perhaps be 1/8" thread on this part? But it´s a German machine...
There are two of theses knobs on the machine, but one is missing, see attached picture.
Any help would be appreciated.
