Tom, you might need to consider changing your user name to "oldercase"
Those are some very nice knives and it's impressive the breadth of the old pre-tested stamps that are represented.
Unlike Tom, my knives are not well organized, labeled, and collected into a single picture. Here are some of my oldies pictured individually. A couple of interesting things to note on these older Case knives is that the shields will frequently be blank and it is common for all the blades to be stamped, including a pattern number.
Tom, did I see a Red Winterbottom bone WR 45 in your group? I was glad to see it - I have one but had not seen another. I have seen WR 45's in Rogers bone a few times.
Thanks for looking.
