Hi Guys,
I'm hoping I can get some help figuring out how the control arm that elevates and depresses the searchlight works. It attaches to the light itself by a horn (seen to the left in this photo http://www.dishmodels.ru/wshow.htm?mode=P&vmode=T&p=2150&id=92496&tp=w
but I don't know if it connects to an external pivot on the side of the periscope, as it seems to on the BTR-60, or it's somehow actuated from inside.

Thanks,
Sean

This is OU-3G Infrared/normal searchlight.

Thanks for the links, I think I've got a handle on it now.
