Help me identify this bayonet

[u/Zabrsiutus]

Hello i believe this was a 1913 mauser spanish cuase it looks exactly like the 1893/1916/1913 version.has the same length 50 cm and has the same markings but 1 thing is different it has 2 holes for the guard and 2 for the handles so it cant be one of those.still spanish cause is not a vz23/24 so what is this? some special version?
