    Re: Kollsman periscopic sextant mount
    From: David Pike

    I’m finally getting around to mounting up my what looks a new and un-issued Kollsman Periscopic Mount late of the Nimrod Force.  Please does anyone know the size and thread of the 24 small screws use to attach the mounting to the aircraft skin?  They look like M4, but might well be a US thread.
