4mm scale model of an Upper quadrant LMR(S)signal of extra height. Working Lamp and Servo Motor fitted. Improved etching Brass Laddering. Bounce simulation is by means of a MERG SEMA4 using firmware slightly modified by myself to simulation both the Pull pause and return bounce, I have implemented 3 variations. Of course this is only available to MERG members. Similar effects can be obtained using commercial servo controllers but these are usually more expensive.

Please note the video may show sequences of other signals as well.
