Congratulations on your new collection!
Kris 1:
Looks to me to be a crossover Maguindanao/Sulu blade with a recent clamp. I also think the hilt is much later, made of gold plated brass filigree. But the ivory pommel looks to me to be a later carving style and the patina might be artificially done to make it look older (an old Filipino/Moro trick for quicker sales). Blade might be turn of 20th century. This type of hilt is for datus and other nobility.
The scabbard is new and Sulu.
Kris 2:
This is truly nice - a great and fantastic Maranao blade! The pommel is nice burled and patina narra wood. I find this the best of the 3. Maybe for a high ranking warrior but not a datu?
The scabbard is recent, but truly Maranao in okir and wranga (top of scabbard) style.
Kris 3:
This kris seems to have an early 20th century crossover Sulu blade. The pommel may be the same time period, though I often see these on 1950s pieces. Not sure if the hilt rings are silver or silver plate over copper (they are newer and I have seen plated copper before).
The scabbard is recent Sulu with aluminum accents through out the scabbard (plates and pins), and sections of mother-of-pearl, and colored bone inside plates of carabao horn. The wrappings are rattan.
Kris 4:
This kris appears to be from the end of the 19th to the turn of the 20th century. The blade is Maranao but the clamps seem Sulu-ish to me. The pommel style is danganan and is somewhat rare, being made of solid horn. For a high ranking warrior or a low ranking datu? Good to have the hemp wrap complete with only some of the lacquer worn off. Too bad the pommel "tail" is broken off.
All of these kris could use some acid etching to bring out the different laminations in the blades, which they did.
I hope these answer some of your questions. You are off to a good start!
