Have you tried Bill Lopouls' site at      http://www.magnetoparts.com/maytag_mag.htm 
He lists Matag Twin coils and information about them.  
One thing that you may already know, with this type of ungrounded, double ended coil, you never want to let it work with one end open, either have it connected to two Spark Plugs or ground one end.  Otherwise the voltage may go high enough to punch through the insulation.
