Bira
Gun
Notes: In the
early 1900s, the Nepalese Army asked the Indians and the British (they were not
a colony of Britain, but had exclusive arms contracts with the British) for some
of the then-new machineguns. The
British and Indians feared that the Nepalese would copy any machineguns they
supplied the Nepalese with (as they did with almost every weapon the British had
already supplied them). This would
not cut into arms sales to Nepal, but the British also felt that these
machineguns would proliferate to Northern India, various Himalayan nations,
Tibet, and possibly China herself.
Britain and the Indians would therefore lose a great deal of money, even if the
sale to Nepal was only a small one.
The Nepalese
then tried to buy Gardner and Nordenfelt guns from other sources, but they were
unsuccessful. Undaunted, they then
began work on their own rapid-fire weapon.
Though they did not have the facilities or expertise to build an actual,
self-loading machinegun, they took a cue from the American Gatling Gun and
designed a very large crank-operated machinegun, using two barrels and fed by a
pair of pan magazines mounted above the receiver, and mounted on a large,
wheeled carriage. (The whole affair
was absolutely huge!) The Bira Gun
even got the US Army and Marines interested; not trusting self-loading
machineguns yet, they looked at the Bira Gun closely, to the point of buying a
Bira Gun and testing it. A then-new
company, Pratt & Whitney, also tested it and told the Army that it was much
better than their Gatling Guns, but in the end the Army and Marines decided to
keep the Gatling Guns. The Bira Gun
was named after King Prithvi Bir Bikram Shah, who reigned in Nepal at the time
of the Bira Gun’s design. It is
believed that only 50 were manufactured, as no Bira Gun with series markings
higher than 50 have ever been encountered.
Several Bira
Guns were bought in the 1970s by Interarms, but these lacked their feed blocks.
Since then, the remaining Bira Guns were acquired by International
Military antiques in 2003, and these are complete.
The Bira Gun is
obviously based on the Gardner Gun, especially in the internals and feed system.
It is a crank-fired weapon, so it has a rate of fire that depends on the
soldier doing the cranking.
The rate of fire for the Bira Gun in sustained fire operations is one-third the
Strength rating of the operator; this may be quickened to one-half the Strength
rating of the firer for 20 minutes, or 3/4 the Strength rating of the firer for
10 minutes. Firing at a normal rate
does not count as fatigue, but firing at a rate of fire 1/2 the firer’s strength
counts as one level of fatigue, and firing at 3/4 of the firer’s strength counts
as two levels of fatigue. Willpower
skill may affect this. Recoil for
“automatic” bursts is equal to 1.5 times the amount of rounds which are fired.
Unusually for the time, the crank turns counter-clockwise. It is mounted
on a large, wheeled, heavy carriage reminiscent of the later DShK; the carriage
weighs an astounding 365 kilograms, with the gun itself weighing 43 kilograms
with the two magazines loaded. (It
was employed by the Nepalese sort of like an artillery piece.) Since the
Nepalese had a large amount of Martini-Henry rifles and even more ammunition for
them, the designers decided to chamber the Bira Gun in the Martini-Henry’s
caliber (therefore, despite the large-caliber rounds it is chambered for, it is
still firing rifle-caliber rounds).
Parts are almost all massive, and this largely causes the gun’s heavy weight.
Construction of
the gun is largely of iron and steel, with the carriage having wooden, iron-shod
wheels. The wheels controlling
windage and elevation were made of brass, as were the gears operating those
components. The sights were also made of brass. Bira Guns could not interchange
parts with each other, since they were essentially hand-made. In most cases,
even the screws holding the gun and carriage parts together had to be labelled
for the place in the gun where they were used, as the screws could not even be
interchanged within the gun itself. Spare parts were usually made for each Bira
Gun at the time they were needed.
The Bira Gun has twin barrels 41.3 inches long, giving the Bira Gun pretty good
range for its cartridge. The
barrels are tipped with rudimentary, essentially useless flash suppressors.
The gun is fed by twin pan magazines, an idea borrowed from the then-new
Lewis Gun. They were mounted one
above another, and the feed mechanism was almost Rube-Goldbergian.
Fire came through the right and left-hand barrels, with the barrel fired
alternating after each shot. That said, the Bira Gun is simple for the soldiers
to operate and reload, and the guns were generally accompanied by several
pre-loaded magazines. The sights
are also easy to use; two sights are mounted on the gun, one for point-blank
fire, consisting of a simple rear groove and front blade, and one for long
range, which used the same front blade and another graduating blade at the rear,
acting as sort of a leaf sight.
The only known
combat use of the Bira Gun was in the 1897 war with Tibet, though some remained
in the Nepalese Army inventory until the 1920s.
The firing stats
below are based on an average-quality gunner with an STR of 8 at a normal rate
of fire.
