Len,
I agree with all the gentlemen who've commented previously,
a wonderful find for your collection. When we get to see examples like yours, it does the heart good ...
As a quick aside ... I know most of these boys who've given opinions so far, and they're pretty tough customers when it comes to dissecting and grading German edged-weapons. You've got a resounding "thumbs-up" from a very tough crew.
Congratulations, and thanks for the fine photos.
Best!
Bill W.
