I'd like to have one of the Queens, the ones I've had my hands on sure look like nice knives. You can actually get pretty good deals on some of the older ones on ebay. The older Case knives command a lot more money than a Queen from the same period. Queen has made a lot of knives for other companies, including many of the Case Classic series knives. Some of the older ones may have been cheapies, but they also made some higher end, great stuff back then.
A while back I got the wants for a new daily carry--I've had a Hen & Rooster stockman for years. A really nice knife that has served well but I wanted something new. I was wanting another German knife.
I did some research and talked to a dealer that carries the German brands as well as Case, Queen, and GEC. He said that right now GEC was the best of the lot, including the Germans.
I've now got three GECs, and couldn't be happier. Two are Northfield and one is the Tidioute brand. Top rate fit and finish, the springs are flat and flush at closed, open and half stop, and I like the 1095 steel. The springs are stout. I carry all of them--not quite, gave one as a gift, but I carried it for a while.
I've had a few Pumas and the H&R, and the GEC knives nicer in overall quality than those. In real dollars I paid more for the H&R and a couple of the Pumas when I bought them years ago than I did for the GEC.
I've also got some Case knives from the '70s, and I hate to say it but the GECs are nicer than those too.
Expensive but good tools always are.
There's a forum called "All About Pocket Knives" that has a bunch of good guys and info--it's sort of the pocket knife version of this place. They have subforums on Case, GEC, Queen and others.
