Thanks Cameron.
Are you using the existing tripod mount hole on the Eumig as the position for mounting the first smaller knob, and then adding the other diagonally and lower from it?
Are the Seagull knobs used on the side and the Kalimar knobs on the top near the viewer or vice versa?
Also for the larger Seagull knob, is it canon to make this with, or without the clear plastic lens installed over the Bell and Howell inserted knob?
