Hi, first post here! I was hoping if anyone here could help me find more information on a pair of 6" L/50 guns purchased by the Republic of China that were mounted on the forecastles of two Chinese built gunboats Yung Sui (completed 1929) and Yat Sen/Yixian (1931). Richard NJ Wright's book "The Chinese Steam Navy 1862-1945", says they were Dutch, but other sources say they were Armstrong guns from the UK? So far I've been unable to narrow the search down, as there were many different export naval guns matching the scant information I have. Perhaps somebody here could help me track down the origin of these naval guns?
