Sorry to bring this post up from the dead, but I think I can add some useful info to this thread for possible future reference.
The first portion of the engraving I would definitely say looks to say "
Jral".
The Katipunan and the 1st Republic of the Philippines used Spanish titles. "General" in Spanish can be spelled "Heneral" or "Jeneral". The Abbreviation for Jeneral in Spanish is "Jral". It can also be Hral or Gral, but that looks like a "J" engraving to me.
"G", "H", and "J" are typically pronounced the same way in Spanish...so you can use them interchangeably.
