> Anything known about the Thornton-Pickard "Special" shutter, produced

>     The one I have acquired appears to have two blinds travelling in 
> opposite directions so as to provide an aperture as they pass each 
> other at the lens centre.
>     It appears to be all there, but I can't fathom the means of 
> setting and releasing it, so maybe it isn't? If anyone could talk me 
> through this one, I would be obliged.
> Thanks,
