So far so good.
Now look at the gun, gun carriage (can you see the difference) and the propeller "of the First Bulgarian submarine" that our military divers dismantled and the commanders in chief of our naval forces donated to our naval museum in the city of Varna. The gun that adorns our museum is 37 mm. Bethlehem made in USA .It is stamped CANON 37 MM.,#5. ,73 KG.,BETHLEHEM 1903 .It also has a sultan turga of Abdul Hamid II .This means 100% that this gun was in Ottoman service empire. When asked when and why the French cannon, for which there is enough ammunition, was replaced with an American one, our historians shrug their shoulders.
