Same Etching As Shown In Wayne H. Techet's Book Page 235 B & 97.
This is an unmarked blade with a W.K.C. Etch on one side and a
Alcoso Etch Pattern on the other side.
Both sides of the blade are clean and bright as is the handle. Scabbard
has some minor loss of paint, the frog and portepee show normal wear
for their age.
Super Rare piece.
