Help to ID this Q stamped knife

[teufelshund]

Hello and thank you for sharing great pictures and information on one of my favorite collecting hobbies. Long time collector and first time poster. If someone can help me ID this Queen single blade I would greatly appreciate it. So far what I can see with a 10x loupe, there is a faint outline of what numbers could have been to the right of the Q or perhaps faded letters? Also the bone handles are much lighter in color. Very solid, no rivet cracks, snaps open and shut. Shows some blade use but not ground or chipped. I've had this one since 1980. interesting that the middle rivet is nearly 3 times the size of the other 2. Anyway here's the good stuff:

It may have the 'Q Steel' stamp, that would make it a 1958-60 model. It has beautiful Winterbottom Bone handles.
If it is 4 1/8" closed, it would be an #11 pattern.

Yes sir, it is 4 1/8 when closed. The Q letter is sharp and has good detail the rest is too faint to even guess but "steel" does make good sense. Thank you.

teufelshund -- Welcome to AAPK. By the way. Is that user name related to anything I might be familiar with.

Here's a Queen date chart you may want to hang on to. It comes in handy now and then.

teufelshund, catching up on reading the AAPK forum and saw your post in the Queen section. Let me also welcome you to the best knife forum around ! I really like the real winterbottom scales on your knife. Your Queen is very similar to a Case "Slimline trapper". The reason for the larger center rivet is it anchors the spring to the frame as it allows the knife to "walk and talk", while the smaller two rivets simply hold the bone to the liners.
