Little is known about this interesting phaser. It was available during the mid and late 70s by different brand names, which were - apart from the JEN PR III - the JHS PZ III Phaser, the Ricken's PR III Phaser, the Zenta PZ III Phaser and finally the depicted FBT Phaser PF III. The lousily soldered board, only prevented from flying around and short circuiting by a piece of foam - is contrasting with the heavy duty pressed steel enclosure. On the other hand it delivers a lively and swirly phasing effect to die for (though a bit noisy).
