1301)   Some kind of fuel powered lamp, with the structure
        at the top a way to vent the hot gases.

1302)   Belaying pins.  Were placed through holes in the rail
        of large sailing ships were needed to allow lines to be looped
        over the top and the bottom in a figure eight pattern.  They
        could be moved from an area where a line had just been released
        to where another needed to be secured.

        And -- in certain situations, they could be used to "calm" an
        upset crewman. :-)

1303)   This looks designed for breaking up ice buildup caused by
        spinning tires  so you can get unstuck in the winter.

1304)   An early "crystal" radio, with the usual crystal (gelanna (sp?)
        held in poured lead, with a "catwhisker" positioned by the knob
        pointing to the upper right.  Except that in this example, the
        crystal has been replaced by a much more modern germanium diode
        connected between the two thumbnuts.

        Tuning was accomplished by the sliders moving contacts above the
        coil.

        The more modern version still had a real crystal under the
        catwhisker.  Headphones connected to the two binding posts to
        the left, and the antenna to the one to the right.

1305)   Now this is an interesting one -- and I suspect that the glass
        is a diffraction grating used to break the visible light up into
        a spectrum just as a prism does.

        The fine adjustments allow you to place the desired color over a
        sensor or whatever experiment happens to use it at the time.

        I don't see the red glass ball -- but I suspect that it was
        intended as an indicator that the incoming light was hitting the
        right area on the diffraction grating.

1306)   Designed to either roll something like window screen into a
        groove on a frame in the construction of window screen
        assemblies.

        Or -- it could be to cut something (fabric, screen, whatever) on
        a hard surface.

        Now to see what others have guessed.

        Enjoy,
                DoN.
