I'm pretty clueless about this sort of thing, Keith. When your title said "presents from Malta" - I assumed they'd been brought back from Malta, brand new.
The plastic label would indicate into to '90s, I think, I haven't a clue about the other markings and I've never seen the Mdina script looking as if it reads Mdrolo or Mdrell before.
I'm afraid I don't take much interest in post '80s Mdina.
