Okay, photos are finally loaded. I'm guessing that the liners are probably SS. I'm not sure whether or not GEC uses carbon steel liners in any of their other lines, but am pretty sure they use SS. I can't think of any benefit in using carbon steel liners.
What is there to say about this knife that hasn't already been said? Some might question whether, at ~$62, is this knife worth $45 more than a standard Case Sodbuster Jr. IMHO, the answer is most definitely YES! I've disassembled said $17 knife and can tell by handling this one that it is of much sturdier construction. Although the pivot could use some refinement, aesthetically speaking, I like it better as-is than a press-fit rivet. To me, the handle shape is leaps and bounds better than the traditional Sodbuster shape and reminiscent of Kerry Hampton's KHNutbuster. I think the fit and finish is befitting of a $62 work knife, bordering on better than expected. I've only handled a few GECs, but I'm beginning to realize that this is one of their hallmarks.
There are only two things that I can nitpick about this otherwise fantastic little knife. Not negatives per se, but things that I think could potentially be improved (at a cost). First, the edge wasn't hair-popping sharp. I wouldn't really expect a production knife to be any sharper, but I had to try to come up with something to be improved upon

Second, I'd prefer the lanyard tube to be hidden. Note how the lanyard tube is visible in the following photo.
I realize that the rear pin on a typical Sodbuster isn't hidden and can rationalize how this helps save cost (a notch in the spring profile versus another punched/drilled hole). I know a lot of knives use this type of construction. Although I don't prefer an exposed pin/tube it doesn't preclude me from purchasing a knife with it. I have a Queen Mountain Man of the same construction. I think a knife looks cleaner when the rear pin/tube is hidden. This could be done rather easily; however, I have no idea what type of cost impact this would have on the finished knife.
Altogether, I'm very pleased with this purchase. As others have said, it immediately went into my pocket. I'm very optimistic about the future of this pattern. If it came down to producing subsequent runs of this pattern as-is or drop it due to added cost of hiding the lanyard tube, I'd leave the design alone. I'd definitely buy more at a similar price point.
