Bristol family history fair advertised with two different closing times

The Bristol & Avon Family History Society has advertised its Family and Local History Fair for Saturday 17 April 2027 at Turnberries Community Centre, Thornbury, with free entry [1]. Two versions of the society's notice give different closing times: one lists the event as running from 10am to 3pm [1], while the other lists 10am to 4pm [2]. Both versions describe the same exhibitors — family and local history groups, archive offices, national organisations and commercial exhibitors — and both include a free family history talk in the afternoon [1][2]. The advertised closing time is therefore inconsistent across the two notices.
