As great of an description, there's a bit more to this Splicer. I've been analyzing this Splicer for quite a while, and like Willbachbakal said, he could be any guy with a 1930's like attire. To my suspicion, his variant would have been one of the officers for either Lamb or Ryan, mostly because he does have The Great Chain marked on his right arm (either linked or broken, depending on how you look at it), and he appears to have a makeshift video and audio communications device on his holster straps, working almost like Delta's camera and radio. Also, because he has a tightly taped outfit, and his mask is a scuba diver's snorkle attached to an air tank, it's a possible hint that he may be able to go under water, which may explain his heavily Spliced appearance (may be half-altered with Big Daddy gene conditioning?). This Splicer might even be the update to "Rifleman", which if you remember the Breaking the Mold artbook for BioShock, there was an "Aggressor" concept that despite wearing Waders-like coveralls, was equiped with a scuba mask and tank, and had an attached weapon. But like Willbachbakal said, he could be anything, and even an engineer named Mickey Grimes does sound good.
