Along with barrels to protect unmounted cells (sold them over on LFF), I've also made a few sets of plugs to screw into the front and back of Copal 3 shutters while they have no lenses mounted in them. Here are some spares.
The plugs are Delrin, with Copal 3 (M58x0.75) threads.
$25 each, or $40 for a set of two, + shipping. Paypal OK.
