Whatizzit?

Take a look. From my step-grandfathers old wooden tool box. I was going to throw them out, but...checking them out it appears they were used to make/break a current since the point base is insulated from the rest. Maybe an automotive application? I would guess maybe teens/20s? Maybe breaker points in an old magneto?

Your hunch is correct, Bosch magneto breaker units. Definitely of interest/ at least some value.

Yes breaker assemblys for Bosch,,Eisemann,Lucas,,,er,,??

There should be small identifying marks,,

NOTE,,they are mirror immage,,the one on left is the common RH

the one on right is Left hand rotation,,not so common

Mainly Magnetoes in Maine could use em as cores,

Mr.Balenger and wife rewind mag armatures and do repair

on old and new mags,Their two generations of fixing mags

with all the winding equipment,,yes they have a website

and answer the phone,

Thanks all. The ID's are Z and Du6. I understand these are Bosch units. Probably worth 15 or 20 bucks each. Glad I didn't throw them out.
