I want to make some military manufacturer for Malaya, but I can't find any information about it.

If you can't find any informations for manufacturer, consider using British Manufacturer such as Royal Ordnance, because Malaya was Puppet of British, so it could use The same equipment like British, although a little outdated, like if British used Sten in 1939, Malay use it in 1944 :)

That's good idea
I have added a malaysian dockyard, founded in the 1910s

Johore and Malacca produced bauxite before and during WW2. Is this reflected in this mod?
One reference for Malayan bauxite is found at https://archive.org/stream/coalsmetalsinjap36unit#page/174/mode/2up
There may be more sources.
Thanks for the work you do.

Thanks! That's what I want
I have added many steels to Johore, so i will add to Malacca as well

this is for the new Historical Indonesia : Vol .3 though

at the time in Indonesia Revolutionary War, Indo never have any "true" weapon, ship, artillery, but there is a statement, that :

- Indo is always use Allied Weapons like M1 Garand, M1A1 Carbine, M1928 Thompson (although these was used during the Allied Occupation, but at Dutch Occupation these was used too), but also use Type 100 (SMG), Type 99 LMG, Type 99 Arisaka because at that time the Natives was recruited by Japan as PETA (Pembela Tanah Air or Defenders of the Homeland), these soldier was trained by Japan to Combat the Allied Forces.

- for Weapon Manufacturer, you could use PT. Pindad Persero

- from statement above, maybe you could make weapon sprites for Indo by Mixing Allied and Japan weapons

- for the Division, you could use name like : 1. Tentara (Reserve)
2. Tentara Keamanan Rakyat
3. Divisi Artileri
4. Divisi PETA (although this can be disbanded by event following Indo Independence)
5. Divisi Polisi (Police Guard)

maybe thats all i can provide, goodluck m8 :)
