Question Bosch Magnetos

Does anyone here on the list know where I could get a book or website that tells what old Robert Bosch magnetoes go to. I have 2 single cylinder mags that are very similar but not exactly alike. Also one has an aluminum band and the other is brass.Niether one has a gear on it...just a coupler of sorts that come off easy to reveal a tapered shaft with a half moon key.

Looks like American Bosch Mags to me. They were used on IHC engines.they were a generic Mag used on any engine that you could adapt it to using a sparkplug, kind of like Wico EKs .The Edwards engine used them but they had two leadout towers,for two cylinders.The guts on these mags is identical to American Bosch AB-33s.Most Robert Bosch mags were made in Germany and used on tractors and the see a lot of Bosch mags used on engines built in England. I subscribe to the Stationary Engine magazine from England and a lot of there engines had Bosch, Lucas, Simms mags on them from what i see in the pictures.

The one on the right is a FX-1 used on IHC the type "M" engines from late 1922 to 1934 ( last one 6hp M ).

Tip: Make your pics a little larger, by that it's easier to see for us

The FX1 ED-4 mag was used on Jacobsen 4 Acre Mowers with the 2 cycle engine, approximately 1925-32. The FX 1 ED2 I have is mounted on an Arrow K-2 engine that is mounted in turn to a fire pump. This unit was built in 1917 in Newark NJ, and was used by the Hainesville Fire Dept until the 1950s.
