I just received this 1961-71 Queen #2 in Winterbottom synthetic. It has a blade etch (it is faint and did not show in the picture, but it is there) that says "Queen Steel #2", and there is no tang stamp. Here ya go Bruno!

Thanks.
Here are the two that I have.
The first has a "Q" ueen tang stamp with the long tail which puts it around 1973-75. Its blade is etched.
The second has a "Q" ueen stamp with a crown above the Q. I'm guessing this stamp was used circa 1971 and then transitioned to the long tail stamp. It might have had a blade etch but if it did, it's long gone.
Both have delrin handles.
You'll notice that the pin sizes are different.

If anybody has this pattern, please post what you have so we can compare them. Thanks.
