Looking for a good GM-20

[MechEng3]

I have a very fast shutter, Iris type, but I would like to find a gm-20 for a shutter on the beam table. Anyone have any they are not using? Let me know.....

Are you selling the 'Iris type' shutter? If so, can I have a few more details and a price as I may be interested, please PM me.

I have found what I was looking for ...... a member has already been paid for them. Thanks. The iris type shutter is from some older video capture device that was stripped for the Trichro and a few other odds and ends. I may consider selling or trading....I need to wait and compare size and speeds......
