Robert, You're right: Packard Shutters.
I guess I was just being cheap. I did a quick Google search and came up with
the Hub Photo page.

The shutter sizes go all the way to 8" diameter openings. The prices are
reasonable. I couldn't tell what the range of time settings were, flash sync
and if they go behind the lens how you adjust and set them?
