Barred Numeral Cancels - Wrington, Yatton

Wrington, 13 miles SW of Bristol, was in the Bristol Fifth Clause Post from 1805.  It was issued with post office number B23.

Yatton, 14 miles WSW of Bristol, became an RSO in 1861 and was issued with post office number B21.

The following three postcards with "B21" 3HOS cancels were sent within Yatton and do not have any date markings.  Based on the KEVII stamps they cannot be any earlier than 1904.  The 1911 census indicates that the Hiam family had moved to Berkshire by then so they cannot be as late as 1911.  Eva Hiam was born c.1901 and Cecily c.1904 so it is probable that the cards date from 1904-1906.
