the early days, not only in Russia but in England and Gcrmanv as well.

In a military publication dated 1912 there appears a mention of a new version, Model 1910, which differs from its predecessor in the substitution of lighter materials, thereby reducing the weight to 54 pounds with water jacket filled or 44 pounds dry. The favorite Soviet system of mounting for the Model 1910 is ihe Sokolof two-wheeled arrangement, which has also been used with very little deviation for over forty vcars.

The outstanding feature which appears in recent modifications of Model 1910 is the tractor-type radiator design used on the water jacket to expedite filling. This design was originated by the Finns and copied by the Russians. The steam and overflow pipe is very similar to the kind used on American heavy farm machinery.

During the decade preceding World War I, all the nations of Europe were interested in the advent of the light machine gun. or machine rifle. The influence of the Maxim gun was strong during this period. Most interest was concentrated on gas operated weapons of the fixed barrel type, but in Russia there was little activity in this direction. How-ever, the reliable action of the Maxim gun which had been imported from England had been incorporated into the thinking of military men in Russia.

Soon after World War I, the Russians made a conversion from their ground Model 1910, making a fixed weapon adaptable for aircraft use. Its official designation was PV-l. This type differed from Model 1910 in that it had an improved type of booster that gave it a substantial increase in rate of fire. The barrel jacket was slotted to allow air cooling, and provision was made for the installation of a synchronizing gear. Infantry rifle cartridges were used; they were fed by means of a metallic

belt. The weight was considerably less than that of the water-cooled model; the finished product weighed only 31.7 pounds.

Shortly after the end of the war with Poland., an attempt was made to lighten the Maxim and produce it in an air-cooled version. The design of this particular weapon was under the direction of F. V. Tokarcv, and it was designated M T to indicate, Maxim-Tokarev. Tokarcv was doubtless inspired bv both the Geiman Parabellum and the British Vickcrs. The arrangement of the trigger and the shoulder stock resembles vers strongh that illustrated in I nitcd States Patent No. 9421(>7, which was granted in 1909 to Dawson and Buckham, assignors to Vickcrs.

'Fhc M- I represents another refinement of the Maxim principle, the main dilicrence from the Maxim being its method of mounting. It has two

metal legs in front and a wooden stock that fits against the operator's shoulder. This weapon was chambered for the standard 7.62-mm infantry' rifle cartridge.

In 1928, a test of the M T was announced in the Russian press. Publicity was given to the event as part of a campaign to encourage native inventors and to promote production of automatic weapons.

A sufficient quantity of the M-T guns was made up for troop trial. The troops pointed out certain objectionable features, and when these were added to changes suggested by the factory engineers, it was discovered that the whole added up to a basic change in mechanism that had to be redesigned in its entirety. Thus, the principal advantage of the original design, the possibility of producing the action with machinery used for Model 1910, was

lost. The Maxim-Tokarev appeared in battle for

the first time during the Spanish Civil War and later in the war between Finland and Russia.

In competition with tin* M T was another version of the Maxim. This gun was modified bv Koleshnikov and therefore called the M K (Maxim-Kolcshnikov). It differs outwardly from the M T in the shape of the stock, but otherwise there is little difference. Kolcshnikov was not successful in securing adoption of this weapon, but enough were made for trial to allow its use in the Spanish Civil War.

A designer of the same name is credited with the development, some years later of a machine gun mount for a calibcr 12.7-mm gun that was then being issued to the Russian Infantry.

There was still another Russian version of the Maxim, inspired by the German T. u. F. of World War I. The Soviets accomplished the design by simply scaling up the rifle-caliber weapon until it handled a 13-mm cartridge. It is sometimes known as the Esiunin machine gun from the name of the engineer who is credited with the design.

With Russia s defeat and the Czars overthrow, the Bolsheviks were slow in getting the country's production potentialities under control and almost nothing was done in the development of machine guns, other than trying to modify a number of Maxims left over from imperialist days to use a 13-mm cartridge. This work was first attempted in 1926 at the principal government arms manufacturing arsenal (Tulski Oruzhcnic) at Tula, where K. Esiunin was design engineer.

In an official test, the prototype had a rate of fire of 300 rounds per minute. At a distance of 120 yards, it would penetrate a thickness of 30-mm of armor plate. Only a few heavy machine guns so modified were actually made; in fact, records show that only eight were delivered and these were distributed among the instructional departments of the Moscow garrison's military educational establish-

Federov "Automat." One noteworthy departure from the Maxim design involved two names now well known in this field of endeavor. In the earlv

nineteen hundreds, Captain of the Guards Vladimir Grigorevich Federov worked on a design for a fully automatic shoulder rifle. In the course of his work, at the Proving Ground at Orenienbaum, he met a young soldier who had been a machinist at the Tula factory, Vasiliv A. Degtyarcv. The meeting was the beginning of a long association, which lasted until Degtvarev died.

In 1908, these two men were working at Sestorets Fire Arms Plant; at the same time, Cossack F. V. Tokarev was working there on another automatic rifle design. Other systems were under development by Roschepci, Schukinn, and Frolov.
