I've recently had the pleasure of obtaining a great 12/3/6/9 Aqua Lung from the original owner who was a Master Sargent in the US Air Force and helped explore the idea of pararescue on their squad!! Like one of my close friend's piece and interestingly enough, this also has a Microbille case versus the much more commonly seen polished case. But compared to his, this has a rather different and unique crown: being the larger crown seen on later No Radiation Fifty Fathom models but is microbille like the rest of the case. Importantly, it also has a 55xx case making me speculate that these all contained microbille cases within the very limited serial range. In addition to the piece, Richard Pambrun, the original owner and an accomplished MSgt of the military, included a narrative of his time in the military and how the Blancpain came into his life....very cool story!! He even states how that crack in the bezel at the 12 o'clock came about in the narrative so just wanted to share with you all Richard's life story. So I'll leave it to the words of the hero himself to tell you the story.
