this is an inductive probe, used in combination with a telephone test set, for locating tone on wire pairs. Most of them are yellow, hence the colloquial name "banana" in the trade. This has the optional blade tip, as most come with a conical and slightly shorter tip. You put the alligator clips from the test set on the two ears at the back and and listen for your tone on the handset while probing the wire bundle with the blade end. There is no "on-off" switch as the alligator clips automatically complete the power circuit on the ears from front to back----untested as it takes an odd 9 volt battery that is shaped little a thick AA battery.--its 8in long and i dont see any maker marks
