I got out my very powerful magnifier and was able to eventually pull up a chewed up barely visible pat no on this
PRESTOLITE breakerless module..
US PAT. NO 34 05 347
I seen during a google search using
US PAT NO 3405347 ignition a reference was made to Phelon at this link.

BREAKERLESS MAGNETO IGNITION, R. E. PHELON COMPANY, INC Sept 8, 1981
and some info at this link

Anyone have any ideas how to cross this pat no to a Phelon magneto module coil or any useable info. ????? Appears maybe this was a Blue Coil of Death breakerless replacement or equal type module?????
