I don't believe the Omega timer boards were interchangeable with U.S. equipment, but some one here may know a heckovalot more about it than me, however, the round push buttons were used by both (although the Reliable button was a bit stoutier than the U.S. design). But to answer your last question..."YEP" there is/was a connection between Reliable and U.S.Elevator but I'll leave that also to the local historians here.
