Rick, Yes happily this is a Constabulary Era piece. I was very excited when I found that it had not only been dated but also that it identified where it was from or at least purchased, something that is rarely seen on most pieces. I am going to try to take a new photo of the toe again tomorrow as it is supposed to be overcast most of the day. Hopefully by taking one in natural light I might get better results.
Detlef, Yes I like many others have fallen into the gunong trap
and have been trying to save enough to be able to afford an early one with an ivory hilt and wavy blade. I know that the ones produced in the 1930's are the most ornate and would love to find one from that time frame with a wavy blade also. My main interest though will always be Philippine transitional weapons from the 19th and early 20th century.
