(Note that the 12.7mm Ho-103 and Ho-104 machine guns are also known as the "Type 1 machine gun", but are actually a 12.7mm adaptation of the M1919 Browning machine gun in fixed and flexible mountings, respectively.)
The reference sentence mentions a 12.7mm Ho-103 and Ho-104 machine gun, which is also referred to as the "Type 1 machine gun". Nonetheless, it specifies that these are not actual Type 1 guns but rather adaptations of the M1919 Browning machine gun in fixed and flexible mounts.
