In the test tank

A Photograph of one of the Thornycroft test tank models, Steyne Wood Battery, Bembridge, Isle of Wight

The light shining through the test tank window can seen reflected on the water and the some of the details of the model and test are written on the photograph. The test tank was constructed in 1910 to replace a former open air one in the grounds of Steyne Wood House.
