This gun was developed in the design bureau of the Perm Factory (MZM). The new gun consisted of a 76 mm barrel (50 calibres long) taken from the 76 mm Cannon Model 1902/30. The barrel was mounted on the gun-carriage taken from the 122 mm Field Howitzer Model 1910/1930. Due to new technological innovations, the barrel of the new gun was more durable than on the original Gun Model 1902, so the heavier rounds (7.11 kg) with increased range (14.5 km) could be used. The gun-carriage was slightly changed for better performance. The hydraulic recoil brake was left unchanged. The wheels remained wood, but their width was increased from 120 mm to 140 mm.

The limber was the same as for the 76 mm Cannon Model 1902, however it carried only 20 rounds, versus 36 rounds for the Model 1902.

According to the Order of 13.04.1933, the MZM factory manufactured six guns for testing. A trial battery was formed and sent to trials at the proving grounds from May 20 to 30, 1933. In September 1933, the experimental battery successfully passed army trials (in the Moscow Proletarian Rifle Division).

On September 23, 1933, Tukhachevsky ordered to accept the new 76 mm Gun Model 1933 because of the insufficient range of the 76 mm Gun Model 1902/30. The new gun received the "F-19" designation and was ordered to be manufactured in both the MZM and Novoye Sormovo factories.

In total, about 200 F-19 guns were manufactured. All further work on the F-19 was cancelled when the new F-22 Cannon was developed.
