Attention Insulator enthusiasts. What is this?

Found this with a bunch of early 1900's artifacts.
Near as I have been able to tell it appears to be a cable support.
It's metal and magnetic.
Am I right?
Anyone know more about the company? A & JMA. Or the number? 1749 (possibly 1743).
Value?
Noboby in our local bottle club that I asked could ID it.
Thanks

Any idea on value?

Sorry, I don't it is at least worth the scrap value? Is it brass? hh

No value, it's had all the ceramic broken off, and even intact those types really aren't collected to the point where that have any collector value.

Albert and Johann M. Anderson Mfg. of Boston. They made electricalsupplies and apparently supplied ordinance to the US military in WWI.
