Vintage Brushes - Can you ID?

I spent last summer in Spain and a relative of my wife - himself in his mid 80s - handed me the brushes below that belonged to his (!) father. So I have no idea how old these brushes truly are. Certainly 40+ years.

These seem to be:
Blue Handle Horse Hair brush (17/50mm)

The Acrylic Handle brushes (15/48mm) seem unused. It is not badger for sure. Looks like boar, which would make sense, but has a feel to it that is almost "synthetic".

They are non-branded or the branding is no longer visible, but probably from Spain (Vie Long?).

Let me know, if you recognize either brush.
