General Liu rifle

At the beginning of 1914, Liu contacted the Pratt & Whitney Tool Company in Hartford, Connecticut to purchase machinery for the Hanyang Arsenal. A contract for US$1,082,500 was signed with the company on 11 April, with delivery expected in 24 months. Later that year in September, Liu—along with his family and seven subordinates—arrived in Hartford, with the purpose of the visit being to familiarize themselves with the machinery. Liu stayed in Hartford at least until June 1915.^[5]

On 8 September 1916, two versions of the rifle were tested at the Nan Yuan Proving Ground in Beijing. The first version was made at Hanyang with a hand-made driving spring, the second was manufactured at Pratt & Whitney and had a machined spring. Testing revealed that the hand-made springs proved to be too weak to properly cycle the rounds, as opposed to the ones produced in US.^[6]

In 1918 two rifles were tested at the Springfield Armory by Julian Hatcher.^[7]

The machinery purchased in 1914 was loaded onto a boat for delivery to China, though the vessel sank in transit.^[8][when?] In 1919 the machinery was recovered and arrived in Shanghai, where it was kept in a warehouse until 1921, when it was diverted to Gongxian Arsenal.^[1]

In the summer of 1919, Liu suffered a stroke which caused paralysis of one side of his body.^{[8][relevant?]}

After being sent to Gongxian, the machinery and tooling equipment was later redirected back to Hanyang but it did not arrive until 1935. When the machinery arrived at Hanyang, it was set up and initially used to manufacture Hanyang 88 rifles, and was later changed to produce Type 24 Chiang Kai-shek rifles.^{[citation needed]}
