The first twelve Gloster built machines were delivered before the end of 1937, and the first Sabca assembled machine was delivered in April 1938. Gloster-built aircraft were given numbers G5-1 to G5-15 before they left Gloster’s factory, and Sabca-build aircraft were registered with numbers G-17 to G-38.

So G.5 appears to be connected to Belgian Gladiators.
