Bob,

    You mentioned old so I assume that I qualify.  I have 3 Tatone  B pans.  Two are new and one has had a wire skid attached lengthwise on the bottom, running from 3/4" from front to 1" from back.  This one is broken about 3" from the back but held together by the wire skid.  It has been drilled and tapped     for engine, tie downs and stab.  It has separate pads for engine and tie down where other pans have one long pad.
