Based on Nahar Singh's research, the weapons of Guru Gobind Singh, barring the swords, were traced to Lady Lindsay, the great grand-daughter of Lord Dalhousie. On the request of the then Prime Minister, Lal Bahadur Shastri, she returned the weapons and now they are displayed at Anandpur Sahib. The search for the sword continued. Tracing the Guru's sword became Nahar Singh's life's mission. After a research of almost 20 years, in 1986, he traced the relevant documents in the archives in 1986. The correspondence between the Punjab Government, the Government of India and the Secretary of State, England, gives the history of the swords and their final disposal at that time.

The search for the missing swords started in 1921 by the British with the efforts of Sir Surinder Singh Majitha (1871-1941). The British felt that it would be a good gesture and "politic to return the swords and any other arms of the Guru if and when available to the representative of the Sikh community."

The search for the swords was carried out for short-term political gains and not with the sincerity and earnesty it deserved. Documents confirm clearly that the final destination of the Toshkhana sword was the British Museum, London. However, the British were unable to locate this in the museum. No document of its removal from the museum could be traced, hence its whereabouts are not known.

There is a brief mention of the Raikot sword in Sikh history. It was gifted by the Guru to Rai Kalha of Raikot in 1705 as a goodwill gesture. Further details about the sword were known through the communication on the subject between 1921-28 traced in the archives by Nahar Singh.

After the battle of Chamkaur and after traversing the jungles of Machiwara with Mughal armies in his pursuit, the Guru escaped by disguising as Uch-Ka-Pir(saint of Uch) with the help of two Pathans. When the Guru reached Raikot, he was welcomed by an influential Muslim named Rai Kalha, who was chowdhry of Jagraon and Raikot. The Guru stayed with him for sometime and here he received the information of martyrdom of his two brave younger sons at Sirhind, and the death of his mother.
