These are vintage Maxon humbucking pickups. Maxon started in the 1960's as a guitar pickup manufacturer and made pickups for many popular guitar brands including Ibanez, Aria, and Greco.
These pickups have a chrome finish and feature a black pickup ring. The poles are fully adjustable as well as the pickup height. They are excellent sounding pickups and are of the highest quality. These pickups were all made in Japan.
These pickups are new/old stock and some of them have a bit of rust or pitting in the chrome finish.
