Butlins Holiday Camp Staff Bar Badge silver plating worn

A scarce original late circa 1946 to 1954 period 'Butlin's Holiday Camp Staff pin badge'; silver plated rectangular bar inlaid with blue enamel inscribed 'BUTLIN'S STAFF', the reverse with maker's details 'Fattorini & Sons Ld Bradford Works Birmingham' (a pattern used between circa 1945 and 1954). Fair condition, complete with original pin fittings, no damage to the enamel, wear to silver plating back to brass base.Size approx 32 x 12mm.Some interesting information accompanied this badge, stating it was used by staff at the Blackpool Camp, however I have been unable to confirm this.
