Right:  In  "Silent"  mode  this  Powers  6B  has  a  brass  lens
        mount with a Dallmeyer lens and rack and pinion focusing.
        The front 3-bladed shutter was standard for Silent Pictures
        at 16 fps with the handle being turned at one revolution per
        second.  The  handle  is  nonstandard,  being  slightly  longer
        than  the  original  Powers  handle  (now  like  "hens  teeth")
        making it easier to crank. The aluminium die-cast frame is
        nickel plated, as are all the brass gears, with one fibre gear
        (that eventually chews out) in the intermittent drive.

                                an  Australian  made
                                lens  plate  with  an
                                improved  mount  to

                                square   cornered

                                gear shield (arrowed)
                                added  because  this
                                was the machine that
                                chewed up my finger.
                                The 2-bladed shutter
                                is  normally  used  for
                                projectors running at
                                sound speed (24 fps)
                                c. 1929 onwards.
