When I was at the factory in August I was told the same thing. They weren't able to get enough of the jigged bone, so they ran the QC in the sawcut. I don't like the sawcut as much, but it's still really nice after it's gotten some use. From what I understand, Queen gets their bone from Culpepper. I have a hard time believing that there is any large scale issue with the dye on any Culpepper bone. Any company is capable of putting out a lemon here or there, but Culpepper has established a name for having some of the best materials in the business and it would take a lot to convince me that there's an issue with the bone that Queen is getting from them.
As for the 49 pattern, it's easily one of my favorites from any company. I've got one the 49QC in the sawcut:
And the regular Queen run in D2 with bone stag or stag bone (they call it both depending on where you're looking):
I don't have a great shot of the D2 version because the bone comes out real dark in my pictures. So, I either get the washed out blades and shield like the above picture or bone that just looks flat black. I figured the picture that shows the bone is more helpful, as you already know what the blades will look like.
Anyways, it's a fantastic pattern. I have never owned a Case '75 to compare it to, but one is definitely on my wish list. I bought the Queen City mostly because I thought that the stamped liners were cool. I never thought I'd carry it and like it so much. It has won me over, though. These two and one Schrade are the only stockmen I've owned where the blades had no rub at all. I like that a lot. I also like that the spey is long enough on these to be useful. In a perfect world the length on the spey and sheepsfoot would be reversed, as I don't have a need for a long edge on a sheepsfoot blade, but of course I'll side with tradition and say that this is about as good as a stockman can get. If you're not opposed to carrying such a large knife I don't think you could do much better than a Queen made 49.
Thought I'd add a terrible shot, which is the best I could muster, of the stamped liners:
