The coil turns fine, the moving contact moves fine, it just need someone to clean the coil and the grunge between the winding's. As such, i'm listing it for much less than what its worth.
It's identical to an eff johnson roller inductor it's marked Lapointe it's the same construction, same 18 uh. It's sort of grungy and unlike the others i've sold here, this one needs a cleaning.
I'll even throw in free shipping. Last 2 photos actual coil, showing worst side.
