George V and Queen Mary are rowed down the Henley course in the Royal Barge, by a crew of watermen. An associated note by Tim Wilson records that Dick Phelps identified stroke as Ernie Barry and 3 as Clasper (though unclear which of that family).
The identification of this crew as the 1926 Thames Cup VIII is not absolutely certain but the members of the crew appear to correlate with other photos of that year's crew.
