Anyway, as much as I know is that one first stage is marked Aqua Lung on the yoke handle, the other is market US Divers on the yoke handle. The second stages are marked Aqua Lung on the purge button, discolored mouthpiece, and Aqua Lung on the purge with Conshelf V! on the faceplate, with the gag strap looking thing. If it helps, the exhaust T is screwed into the reg. The Micra is just marked US Divers Micra, and it's gaudy af.
What do I have (beyond the obvious), which should I keep, and anyone want to make an offer on the rest of it? I will literally never use any of it except the one second stage just so I've got something "matching" on my Kraken
