[A. G. Maisey]

Semar, sumur bandung is a confusing pamor, it is confusing because it has the form of several empty round circles, or a couple of empty oblong circles separated by a puser. Two distinct forms, with the main characteristic of a framed area of blade that is empty of pamor.

You have shown us the second type, with framed empty oblong areas separated by a puser.

Jean has shown us a blade with a series of dots, which if one has never actually seen a sumur bandung pamor, and only had book pictures to refer to, could possibly be mistaken for the second type of sumur bandung.

In fact, in Jean's example the dots are not big enough, not few enough, and not distinct enough to be read as sumur bandung. But from a book reference, could easily be mistaken for this pamor.

PS --- if you would like confirmation of what I have said, I have just checked Ensiklopedi, and Harsrinuksmo says just about the same as I have said. Page 446.
