Hey Lew, i think you might have scored a few nice blades there. In the pic of the four blades the one on the left is an old kebo form, a dapor suitable for those in the agricultural fields, the next one over looks like is might be peninsula work, but i could be wrong. Regardless it is very well formed. The next, which is probably Javanese, seems solid, but average. The Bali looks nice, not a full ricikan blade, but still well formed. The short little blade with the Sumartran sheath looks to be an old patrem or women's keris.These are somewhat scarce. Does it proper fit into the sheath? I can't wait to see what kinds of pamors rise to the surface of these as you restore them.
Finding hilts for these probably won't be too much trouble, but properly sheathing them will. You may need to send them overseas for a while and at a price quite a bit more than you paid fot the blades themselves, but it might be worth it in the end.
