Hey, there is something about the Chinese fighter planes I'd like to discuess here. According to following refenerce I checked, the second fighter in line should be XP-0/1/2. Kind of like XF-35, X should mean "in reserach, concept demonstrator".

Refenerce:
Andersson, Lennart. A history of Chinese aviation : encyclopedia of aircraft and aviation in China until 1949. Taiwan: AHS of ROC, 2008. Print.

i know by the time a prototype was built it was already obsolete i want to replace it with the P-47 Thunderbolt.

What sort of artillery pieces did the chinese have the capacity to make or use?.

Well china in the 1920 have varies 75mm,105mm,150mm, and 155mm field guns, mountain guns, and howiters. In the 1930s produced in small numbers of home produced german copies from WW I and imported small numbers of leig 75mm infantry guns, lefh 18, and sfh 18 From the S.U. 76mm field guns. From Sweden 75mms From Italy 75mms. In the 1940s China got a lot of US 75mm pack howitzers, 105mm howitzers, and obselete 155mm howitzers. Captured a lot of Japanese artillery from 75mm to 155mm. In the 1950s from the US 155mm Howitzers Long Toms and up to 240mm howitzers.

For Support Weapons III, China is able to get the M1919. I'm quite interested in Chinese small arms myself, and I've been doing some research on this.

Apparently they made a copy of the M1919 during the Warlord Era, then some OSS-trained divisions were able to use the M1919. I can't really find anything further on this.

So did they manage to get the M1919 in large numbers, or was it only during the second Civil War?

yes china did get the m1919 due to lend lease and they produced them unlienced. they were use as tank machine guns and normal machine guns

Cool, thanks!

no problem
