Wipac "Geni-mag" flywheel identification query ?

[Stephen Foster]

Wonder if any forum member can help Me identify the above please ?
I am aware that the later Wipac unit is marked up AC/DC with 6 magnets around the circumference .
I am trying to establish if the 1949 "Geni-mag" has 3 magnets only & if it ought to carry an identification mark ?
I have searched in vain for a Wipac parts list & really need to find the information urgently ?
 
Thanks in advance ,
Steve ...
