Well , that pushes the integral gangya back to at least 1906 if we are to believe the info on the site .
Another thing that is pushed back some more is the sharper corners on the seki(sp?) which I had equated more with the mid 20thC. era .
Interesting ..........
So does this mean that Cato's 1930's seperate gangya guideline is out the window ?
Or are these two kalis just anomalies ?
