Used for "When the Levee Breaks", as mentioned by sound engineer Andy Johns in this MusicRadar interview published October 31, 2013.

"I used two Beyerdynamic M160 microphones and I put a couple of limiters over the two mics and used a Binson Echorec echo device that Jimmy Page had bought. They were Italian-made and instead of tape they used a very thin steel drum.

"Tape would wear out and you'd have to keep replacing it. But this wafer-thin drum worked on the same principle as a wire recorder. It was magnetised and had various heads on it and there were different settings. They were very cool things!

"And so playing at that particular tempo on 'Levee the limiters had time to breathe and that's how Bonzo got that 'Ga Gack' sound because of the Binson. He wasn't playing that. It was the Binson that made him sound like that. I remember playing it back in the Stones' mobile truck and thinking, 'Bonzo's gotta f**king like this!' I had never heard anything like it and the drum sound was quite spectacular."

Terry Kath is noted for using the Binson Echorec B1, as detailed in "TK's Gear" on The Terry Kath Experience website.

Toward the end of the century, when Isao Tomita sat down to record the piece, he had before him a thicket that included a Moog synthesizer, comprising (among many other things) a 914 extended range fixed filter bank, two 904-A voltage-controlled low-pass filters, nine 901-B oscillators, four 911 envelope generators, five 902 voltage-controlled amplifiers, a 950 keyboard controller and a 6401 Bode ring modulator; several tape recorders, among them an Ampex MM-1100 16-track and a Sony TC-9040 4-track; two Sony MX-16 mixers; an AKG BX20E Echo unit; an Eventide Clockworks Instant Phaser; two Binson Echorec 2 units; and the electronic keyboard instrument known as a Mellotron.

Beyond epic tone party with my friend Keith Nelson today. Video tomorrow.

Peter Banks is noted for using a Binson echo unit. While the source from GuitarPlayer.com does not specify the exact model, it indicates his use of a Binson echo machine, which could likely be the Echorec B1. Further confirmation would be valuable if additional details on the specific model emerge.
