I'm not going to add you much work this season, but I'll dare to refresh some of previous suggestions:
2 T-26 - photos of Chinese tanks are at
http://dlyakota.ru/61544-tanki-t-26-v-kitae.html , and I'll also attach one.
7 Type 95 Ha-Go - one of MGs should be #245 TMG, like in Japanese unit (although it could not be used at the same time, as a cannon)
9 M5A1 Stuart - basic wartime model surely was M3A3 (which is on the photo). According to
https://en.wikipedia.org/wiki/M3_Stuart , M5A1 were used after the war. Also Zaloga's "Tank battles of the Pacific war 1941-1945" and this exhaustive article
http://www.cbi-theater.com/1ptg/1ptg.html mention only M3A3 in the 1st Provisional Tank Group (besides, it would be unreasonable to deliver tanks with different engines). So, I believe, that M5A1 should be available no sooner, then mid-1945.
A (post-war?) photo of Chinese M5A1:

84 Frigate - it should be renamed Cruiser, which it was.
266 Armrd Truck /MG - here is a photo of an armoured truck used in China (now it's French unarmoured Laffly):

Maybe a better name would be just "Armoured Truck"? Cannon-armed ones were rather exceptions..
There at the bottom are interesting twin-turret armoured cars:
http://www.network54.com/Forum/33033...ed+Car+in+WWII
(there's a perfect icon 2717).
There should be also added Citroen-Kegresse armoured car, of unknown model, used by Wu-Peifu warlord (since 1/30? for several years). I assume, that the armament was 37mm Puteaux gun or MG. Polish unit 663 wz.28 AC could serve as a direct pattern. It should look similar to the French car on the page
http://derela.republika.pl/wz28.htm - or photo 29505 or 29508 could serve.
282-284 L3/35 - L3 were later Italian Army designations, the Chinese would rather use original name CV-35
285 T-26a - Russian sources don't mention, that China got twin-turret T-26 - only single-turret ones (besides, the Russians generally didn't export obsolete twin-turret T-26)
287, 300 VCL M1931/T-37 - name should be just VCL M1931 (it's not Soviet T-37). (I'd call it VCL M1931 Amph or something like that)
Armament should rather be Vickers, not DT.
288 Vickers 6-Ton - users of Vickers 6-ton are well known, and China had no twin-turret Vickers for sure.
289 MHarrington 4TA - "Reportedly China also ordered a quantity; it is not probable that any of these were delivered" (previously from
http://www.warfare.altervista.org/Ma...gton/tank.html).
Also T. Basarabowicz and this Russian article
http://tankfront.ru/allies/china/history.html say they weren't delivered.
295, 296, 298 M4A1, M4A3, M4A4 - M4A4 was surely a main model, and apparently the only Sherman of the 1st PTG, used from 4/44 (
http://www.cbi-theater.com/1ptg/1ptg.html ). AFAIK, the 1st PTG was the only active Chinese armoured unit at that time. Zaloga nor other publications don't mention other M4 variants to be used by the Chinese, especially as early, as 1942/43. The photo used here for M4A3 is also described by Zaloga as M4A4.
376 Type 97B Te-Ke - photo is MG-armed, gun-armed is 4019 or 3736
It's all about the armour, I think.
