Really interesting and (to me) the price seemed like a stonking bargain!

So the napalese king was a smuggler, terrorist, a rebal and in possession of a prohibited machine gun - Life in prison !!!

this is really amazing. You have to give credit that even with reverse engg they were able to make it to production.

It proves another thing, english ppl always dumps waste to us

Can anyone please tell what is the point in having twin barrels? It appears to be a disadvantage because compared with single barreled machine gun, a twin barreled machine gun will empty the magazine in half the time. Twin barrels in some anti aircraft guns is understandable because they have to hit a very fast moving target at a comparatively longer distance, thus has low probability of hitting the target.

The label of "terrorist" or "terrorism" is just a politically motivated label. It can vary from time to time and place to place. For example the founding fathers of America were terrorists in the eyes of British when they made declaration of independence and subsequent war of independence. But once they succeeded in becoming politically sovereign, they were no more terrorists. Similarly Surya Sen, Chandra Shekhar Azad, Kartar Singh Sarabha, Bhagat Singh etc. were called terrorists during British rule but are called freedom fighters once the British left, notwithstanding the laws describing who is a terrorist remain the same.

In short one can generally say those people who are not politically sovereign are likely to get the label of "terrorists" even for their legitimate actions or demands. One the other hand the politically sovereign people rarely get label of "terrorists" even if they indulge in terrorism.

This is true for almost every country. Rarely does any country discloses or supplies the top secret technology giving an edge to another country.

It's a hand-cranked machine gun.The Gatling gun with its six barrels fired 200 .58 calibre rounds per minute. This gun would not fire a lot more than that. Even if at double the rate, it would only fire 400 rounds per minute.

It is very true but doesn't this gun discharge from both the barrels simultaneously? How does firing simultaneously from two barrels almost a foot apart help hitting more man sized targets? If one bullet hits the center of a soldier other bullet will be hitting around one feet away towards left or right of the soldier. Yes it will be useful if trying to hit a large crowd like formation of soldiers standing or running side by side very closely.

The main purpose of Machines guns at that time was to stop the large no of Infantry attack. so to do it, the most convenient way was to pump as much leads as you can in a short time. Bira was also an attempt of that era.

A machine gun is not used for accurate firing as we understand in the context of rifle shooting. Their use is predominantly in providing suppressive fire, defending troop positions, deployment against massed infantry attacks, etc. The WW-1 witnessed tremendous carnage inflicted by machine guns.

The following excerpt gives an idea about how machine guns, at least infantry versions, are employed.

"Beaten zone is a concept in indirect infantry small arms fire, specifically machine guns. It describes the area between the "first catch" and the "last graze" of a bullet's trajectory. At the first of these points, a bullet will hit a standing man in the head, at the last of these points, as the bullet drops, it will hit a standing man in the feet. Anyone standing within the beaten zone will be hit somewhere from head to foot.

The concept works best as part of a static defence with the area covered by a position plotted out beforehand. Usually the machine guns will be mounted on a tripod and indirect fire sights (such as a dial sight) fitted in addition to, or instead of, direct fire ones. Fire can then be called in by spotters to engage specific points in the guns' field of fire, even if out of sight of the machine gunners."

I see, then placing two barrels side by side was a pretty clever idea to produce a good suppressive fire and also hit maximum soldiers in massed infantry attack.

I'm not sure of the mechanism but if the barrels can be made recoil-reciprocating in sync, they can potentially neutralize a lot of muzzle jump!

Muzzle jump is function of how much torque is produced by recoil of the gun barrel. You can reduce the torque to zero if you perfectly align the fulcrum of the gun(recoil pad, butt etc. in case of rifle) with the barrel of gun. Aligning the fulcrum of gun having single barrel is much simpler task than that of gun with two barrels, that too separated by a considerable distance. If the two barrels fire simultaneously, then you will have to align the fulcrum of gun exactly with the center line between the two barrels. If two barrels fire one at a time, then each barrel will need fulcrum to be perfectly aligned with it.
