Weapons and objects associated with the Gurus are held at Takht Sri Hazur Sahib at Nanded, at Anandpur, at Patna Sahib, at Sis Ganj at Delhi, and in a number of private family collections across Punjab.
They include swords, a chakar, arrows, a comb, garments and other items. Several are displayed on specific days each year and drawn very large crowds.
Their authentication is a matter of custodial tradition rather than of documented provenance in the modern museum sense, and no scientific examination has been made of most of them.
A number of Sikh relics and manuscripts are in British collections, taken after 1849 or acquired later, including items from the Lahore toshakhana.
The Nanded weapons in particular are central to the practice at that takht and are treated as devotional objects rather than as museum pieces, which is the custodians' right and which does mean they are not catalogued.
There is no consolidated inventory of Sikh relics anywhere in the world.
At Hazur Sahib the weapons are brought out and bathed in the presence of the sangat on fixed days. That is a devotional act rather than an exhibition, and photography of it is generally not permitted.
Almost none has been examined by anybody with the metallurgical or documentary training to say anything about it. Attribution rests on custody and on tradition.
Objects have been sold abroad and Sikh material appears in auction catalogues regularly. There is no register of what exists, which makes recovering anything stolen essentially impossible.
