Coracle cocktail suitcase with 1955 Booth's Finest Gin bottle.

While cleaning out my parents loft I came upon this suitcase. Looks like it's supposed to hold two bottles of spirits and the associated parts for making cocktails.

The containers look to be plastic, it's missing one of the four glasses. The 4 bottles of soda water are still full, capped and unused. There was also an empty bottle of Booth's Finest Gin, dated 1955. The cork has sheared off at the top where the cork has crumbled away.

The case itself has no dates I could find, and I've struggled to find anything similar on google.

All of the containers are undamaged, there's a separate bottle opener and knife also in the case. all straps are sturdy and working. Some slight scratches/abrasions on the outside but relatively all intact besides that.

Is this worth anything? Either all together or for just the bottle on its own?

Curiosity eating me, appreciate any help anyone can provide.

thanks,

Mike
