with the camera unfolded / open look at the camera (facing the lens )
you should see the focal plane shutter release on the left side.
(its chrome on the black body )
push it in and it should begin to un-tension / fire the shutter.
if you do this 4 times you will go down ( 1000 - 250 - 50 - T )
the next number will be "0" and it will allow you to use your shuttered lens.
it the shutter doesn't release contact paypal, don't bother with your seller,
paypal will get your money back if you ...
having the focal plane shutter wound up all the way to 1000 isn't a good way to have the camera stored
you want to leave it un-tensioned "0" when you aren't using the focal plane shutter, otherwise you'll
stretch out the "spring" ...
