My Indian Army Maxim machine gun is another blister pack from Copplestone Castings' Back of Beyond Range. In fact, the pack comes with two machine guns: one Sikh and one Indian Muslim. When purchasing, since I live in the USA, my go to for Copplestone is either eBay or Brigade Miniatures (no Lon Weiss did not pay me to write that!). If you are in the States, Brigade Miniatures has inexpensive and fast shipping - I highly recommend the store.
The Maxim gun has been called "the weapon most associated with imperial conquest" by historian Martin Gilbert, and was heavily used by colonial powers during the "Scramble for Africa". Afterwards, Maxim guns also saw extensive usage by different armies during the Russo-Japanese War, the First and Second World Wars, and are used by insurgent groups in contemporary conflicts.
