Has anyone a dimensioned drawing of a triple valve they can share?  Any era.  All sides.  Even a couple of photos of drawings will help.

==================

Very difficult to find, and may be non-existent. Since the brake parts were vendor supplied, the railroad only needed to know the locations of the mounting holes, but not the details of the actual valve housings. That info would have been in the drawing files of WABCO or New York Air Brake Co., but I'm not aware of either drawing archive being available to the public, if they were saved at all.

The old standby is to find a drawing that appears to have been drawn to scale and has one identifiable dimension, such as the distance between the mounting holes, which can be picked up from a "steel details" drawing that dimensions the mounting bracket. Or, measure a valve yourself.
