This Packard shutter works well. I have just cleaned it. It is the double piston style. One bulb controls instaneous exposure, and the other one Bulb exposure. The hole measures 3" and overall dimension is 5.75" square. It can fit inside the bellows of a Kodak 2D 8x10.
$75 plus postage. Or $95 included 2 bulb/tubes. Paypal.
