|K57. Not really a telegraph key! Information from the Honorary Curator John Parker at telegraphmuseum.org:
It is probably a testing key, there are different special keys for telegraph cable capacitance tests. Charge the cable from a battery for so many seconds, then discharge it via a galvanometer and measure the deflection or 'throw'. The cable would be connected with the centre, and the battery and galvanometer to the other two.

The knob is molested, and need renewing, otherwise it is operational. Tnx info OM Giuseppe, IK8FYW.||K104. A contemporary Bencher RJ-1.

I don't know the origin of this key, it might be American, but it is made of much heavier and thicker materials than the typical J-37:s. Any info is welcome!||K112. McElroy knock-off(?). Unknown maker. The base is coarse cast iron (magnetic), with wrinkle paint finish. Slightly smaller than a McElroy/Tac, 8 mm shorter and 6 mm narrower base. No shorting lever.
