Unusual Albacete knife

[Sajen]

This run-down Albacete knife crossed my way recently, the edge seems to be several times resharpened, the ferrule near the blade shows some dents and two handle inlays are missing. I never before have seen such an Albacete knife, do you have?
32 cm long, blade with brass bolster 21,3 cm long. Quite heavy with 164 gram.

Last two pics show it together with my other Albacete daggers for comparison.
