1914 repairs at Baltic Engine Works, Goole
The scan below is from the order books of the Aire & Calder Navigation Company and shows the works being carried out in 1914 to 'floating plant'. Item 164 refers to fly boat No.81 (aka Waterdog) and seems to be repairs for £60.
The books are difficult to read but it seems to list 2 fly boats for repairs, No.14 and No.81. The repairs to fly boat No.81 cost £60 in February 1914.
