Kodak manufactured the Cine-Kodak Model K 16 mm motion picture camera from 1930 until 1946. This camera accomodates up to 100 foot rolls and a Kodak astigmatic focusing 25 mm f/1.9 lens. The mechanism is spring driven using a side-mounted winding crank. We do not know the acquisition date.

Standard Pony Telegraph Relay manufactured between 1900 and 1910 and listed in the MESCO 1905 catalog for use as burglar alarm for a given length of telegraph line. The list price is between $3.00 and $4.00 depending on the coil resistance. MESCO states that the relay uses much less power to operate than a sounder of similar resistance. A resistance measurement was imposible as this device has a break in the coil windings.
