Q: dual ended ignition coil

[thomas walter x5955]

Does anyone know of a source of DUAL ended ignition coils?
Production application?  Looks like a coil with TWO HT
leads from it, my 1958 Honda 305 Dream was so fitted so
it is not a new idea, either.

Also, in case there are any 4 cylinder DATSUN fans on the
list, my target is a L16/L20B engines. Just curious if
anyone else maybe building for this engine. 

Long weekend ahead... time to get busy in the garage. ;-)
