The Galvanometer is a null detection device usually used in a Wheatstone Bridge circuit. The balanced bridge is detected at zero volts and therefore does not load the circuit under test. There is generally a light source involved to project a shadow of the indicator on the screen. You may not be able to detect the motion of the movement without significant magnification or by projecting its shadow. The adjustment screws are to level the device and the protective cover (Can?) protects the movement from drafts. There should be some meas of clamping the movement in transit to protect it from damage. Although it is obviously very fragile, all that I have seen are not to difficult to repair. The lubricant I use on pivots is kerosine, only as much as you can carry on the tip of a sewing needle.
Try to help it find a good home, they don't make them any more... I disposed of mine because I did not want them to wind up with an uncertain fate in my estate!
