Thanks Jack for bringing all this to the table again. Very helpful. I finally get your "teardrop" description, as it applies to the coolie caps
I will take this info and find as much as I can on it. Fun stuff.
Again Jack, thanks for giving a considerable amount of time in using your professional training to bring order to dating these knives.
You have been accurate, whether it be dating and identifying sheath maker, dating blade stamps, escutcheon plates, or dating knives by the hardware taking all the above in consideration to do so.
I appreciate all you have brought to our community.
