This is a collection of over 500 slides which I've inherited, so it's an educated guess that they're from the 1960s, although the ones taken in Scotland are marked 1967 and 1968.

The  storage case holds 84 slides of unknown scenery and also slides showing British seaside places and other towns.

The boxes hold slides of Tenby, Flamingo Park, Yorkshire, Norway, Italy, Ireland, Scotland, Holland and Austria.

There are 7 empty boxes and 40 slide mounts.

There are 7 souvenir packs from Firenze, Venezia, Pompeii, Siena, Vatican, Tivoli by night and Rome. 

They are mostly in very good condition although the souvenir packs are showing their age somewhat (not the slides themselves but the paper cases, and some of the glued bits have dried up and been repaired).
