An interesting photo that poses a question. "V" was indeed the flag superior for MTB's, but 252 was a White (of Cowes) designed and built vessel which more closely resembled the familiar Vosper short design, whereas this vessel is almost certainly a British Power Boat Company design. The two canvas covered gun turrets on the superstructure are like those installed in RAF ASR launches of the same design as this vessel. Does anyone have an answer? MTB252 (The White built vessel) was commissioned in 1943.
