With parts left over from my last Argus monster building (Model M21 with Geiss modified lens mount), I did another one.
This one is an early variant C-four with a late variant M21 lens mount.
When I started this one I found out early on why the C-four's shutter was not working. Last person in there had put the shutter blade assembly parts together very wrong, and the blades were locked in place, leading to a break in the linking lever from the mainspring camshaft.
This new monster is now in working order, cleaned and calibrated.
