Butlins holiday camp blue round numbered STAFF badge

A rare original early period 'Butlin's holiday camp staff badge'; gilded brass circular example inlaid with blue enamel inscribed 'BUTlIN'S STAFF'; the reverse impressed with maker's details 'J.R.Gaunt London' and engraved with official low issue number '205'. Very good condition, complete with original pin fittings, enamel perfect, gilt finish remains bright.
Diameter 27mm.

Some interesting information accompanied this badge, stating it was used by staff at the Blackpool Camp, however I have been unable to confirm this.
