O me miserum!
I thank John Moss for setting me on the correct path to righteousness.
I had misinterpreted the idea that WRA had delivered 9mm in “Chinese” packets ( I had seen Chinese stamped 7,92 Contract packs from WCC before). but anyway, the “repacking” idea as an instruction to do, rather than a fact carried out seems strange to me, unless it was done by Winchester from old stocks of “Commercial pack”( English printed) WRA 9mm, no longer required by the British Commonwealth, and re-directed to China (ROC) forces preparing to do real battle with Mao’s Red Army , in the rush to occupy Japanese held areas in the latter part of 1945…The USAAF actually airlifted Nationalist troops into Manchuria to occupy this industrial area when the Soviets pulled out in 1946 or so (Looting and Pillaging the Industrial heartland as they withdrew).
As to the Chinese Use of 9mmP ammo, Canada had supplied the famous
Chinese Contract Browning (HP35)Pistols, and also a large quantity of Long Branch-made 9mm Sten Guns. This was sufficient reason for 9mm Pistol ammo to be supplied to the ROC. Canada also supplied 64-round packed ammo to the ROC (DI manufacture).
The US also supplied the ROC in 1945-48 with a lot of captured German equipment (Rifles in 7,9, and Pistols and SMGs in 9mm)…another reason for 9mm ammo to be supplied.
A lot of the 9mm calibre weapons were evenutally converted to 7,62x25 in the post 1950 era ( I have seen a Long Branch Sten with modifications to 7,62, as well as rebuilt Colt 45s and Browning HP35s as well.-- samples were acquired back in the `1980s in Aust. by a longtime specialist collector with contacts in Hong Kong (and from there to the PRC).
A Note on the “42 round” 45ACP ammo packets…Australia bought a lot of .45ACP from WRA during the war, and all the surviving examples of full packets I have seen on this side of the globe have been the 50-round Commercial pack (I have several with 1941 dates) By 1943, Australia was gradually shifting from the Thompson to the Owen, and the lesser demand for .45 ammo was covered by Footscray (MG and ?MF plants) making .45ACP ammo locally.(Dates 1943-45) The Thompsons were relegated to Naval Shipboard and Shore Patrol, and RAAF Airfield Defence, well into the 1960s. A repeat delivery of .45ACP ammo was made in 1956.( “MF 56 I .45”)
Footscray used a smaller packet (20 rounds, I think, I have a 43 dated packet & will have to check). The TSMGs used in Australia were either 20 round or 50 round magazines for the most part, the 30 round mag had very little use(if at all).
Again, mea culpa…speaking out on matters of which I have only a little knowledge (“A little knowledge can be dangerous!”).
