The Krupp no27 1913 is not a 8 cm Krupp but a Krupp 75 mm C/36 mod 1913.
108 were ordered by Brazil before WW1 but not delivered.
The guns were taken over by the Germans and given or sold to Bulgaria.
The Krupp guns in the closed part forum (Brasilien armoured cars and tanks 1930s) were these guns and not Krupp 75 mm C/28 mod 1905.
The gun on the photo was captured during WW1 and given by the French to Brazil in 1920.
