Congratulations on your great aquisitions. Great looking silver kris.
Does your Jungayan barung have any ivory or bone inlays on the pommel? Usually these types of barungs have triangular and dot inlays of bone or ivory on the sides and decorative inlays on the pommels. Is the pommel made of kamagong or kalabao horn?
These are great swords and would be careful with the hanging method.
