Alternative Ignition coil for points

[bluejets]

Been using BA Falcon coils here in Aus lately, on the plug coils with the tube and spring stripped away (any from BA to BF the same) powered from a 1S 18650 cell and seems to work ok. (3.7V)
Coil number there is M1115L10 for the convenience of anyone down under.
Positive white wire, points black wire.

Thanks for that. I have a couple of those sitting around and I'm in need of a coil soon so I'll give it whirl.
