These shutters really work from speeds 1/1000 down to 1/8. I have been using a couple of them for the last six months.
Let me know what you may think about this lightweight (4.4oz) unit.
Thanks in advance:

Ron,

The Thorton-Pickard that is for sale now is much more expensive and looks to out weight the Gatts/Tincher shutter many time over. I don't have to defend the Gatts/Tincher shutter, it has proven itself time and time again! Reich, do you mean the actual travel speed of the shutter? It falls at 32 feet per second, according to Newton.

As already mentioned, your shutter is not a focal plane shutter. The fact that you sell them as such on Ebay violate also the Ebay policy. You're misleading people with that description.
Also, Newton speaks about free fall. Your shutter is not falling with free fall. If you measured its speed electronically you would find out that you cannot guarantee its precise speed - it has none.
