Hi,

I am looking for an ibsor shutter. I have a lens that mounts to one - unfortunately my shutter is thrashed. I don't know how many sizes of ibsor shutters were available - I know of at least two (one with a 1/125 top speed and one with 1/100 top speed). The current one I have has speeds up to 1/100. The mounting threads on the back are about 39mm diameter. The cells of the lens I have (front and rear threads are the same) are about 34-35mm.

If you have one available let me know (if you have the mounting flange that would be better still).

Thanks for your time
