Thank you so much guys!!!!
Lew, right on! I remember that excellent kaskara, unusual with a distinct trade blade, unusual fullering. It seems that for some time, old kaskara blades ended up in England joined with medieval styled hilts to be passed of as weapons of the Crusades (Oakeshott).
Fernando does indeed have an incredible eye for great pieces, and this one is a very good example.
David, again well thought out! and outside the box
which is the best place to be in trying to really get perspective on many of these great old edged weapon mysteries. Good observation on Andrew (lat./Ital. =Andrea) and the note on St.Andrew, of course Scotland's patron saint.
Your deductive reasoning is great, and much appreciated.
Thanks again for getting this one goin' !!
Very best regards,
Jim
