I have a Liberation Mr P 5.0 for sale. Factory gold plate, although it's considerably paler in comparison to other gold plate mouthpieces I've owned. Single adult owner (me) except for light insertion marks the mouthpiece is in the same very good shape as when I bought it several years back. It was a backup for another 50-style so it didn't get much use. Just been finding in my later years

Of course happy to send a photo, call/text/voicemail 815 793 1223
