For an Eastman Commercial 8 x 10, the 1930ish catalog indicates a Packard #6 shutter is recommended, but it doesn't say what size. It
looks like an 8" square (4.5" opening) would just fit, but later in the catalog #6 Packards are only available up to 7 1/2" (4" opening). The
8" Packards are style #8 with dual cylinders. The camera has 1 plugged hole for the air tube and a mounting spot for the instant pin, and I
want these, especially the pin, to line up properly. Does anyone know which size shutter I should be looking for to fit this camera
properly? Thanks.
