Need help with historic data (for new units) and names of some modelers (to make sure I don't rip off people)

[Grimblade]

Prepare for wall of text or just skip to near end of post.

I have been trying to (and for now succeeding) in adding new models to DLV (though some still need unit cards and unit info cards).
Some units are made by Creative Assembly for M2TW: Kingdoms and since DLV requires Kingdoms to function I guess it is OK (unless from C.A. get me ).
These units are:

-Kingdom of Jerusalem units (work in progress for now just took Constable of Jerusalem) from M2TW:Kingdoms Crusaders XP.

- Spanish Dragoons; really nice model, even made it reload guns quite a bit which I never observed original model do (Thanks to Taiji’s BB) from M2TW:Kingdoms Americas XP.

Just to be sure I don’t rip off anyone or use someone’s model without permission I would like to know who exactly I should ask for permission to make models for these units:

Mounted Cossack Gunners: I made them out of GREAT Cossack Cavalry textures (normal and upgraded) supplied by Rusichi:Total World (or so Taiji’s BB page said) so I need to know who exactly made those (model seems to have been made by CA). Weapons are made by C.A. from Camel Gunners model.
Flemish units: at the moment I am not sure which model I should use to give Flemish some nice cavalry, so I need a bit of historic help too . Basically I can make combined models but not texture or models from scratch . I made Armored Gunners (something like a precursor to Dragoons) , again using weapons made by C.A. for Camel Gunners model and using Flemish Mounted Sergeants (model by C.A. texture I don’t know from who) , then after finding them antiquated I used upgraded Mailed Knights (also C.A. model + unknown’s person texture) and gave them guns. They still don’t look quite right. So does anyone has an idea what type of Armored Mounted Gunners Flemish used or something that I can add that isn’t heavy cavalry with maces since everyone and his grandmother already have them ? Have in mind I can make them only from existing models, for some unit types they don’t have to be from Flemish models if texture already exists but for most others I need to use unit already on Flemish roster (and add it weapon).
NVM ABOUT ARMENIA GUNPOWDER UNITS
Also some units will just have to go if I want to make them usable by limited M2TW engine so my idea was to “murder” Greek, Armenian and Kingdom of Jerusalem siege units (I did of course gave them an ability to still produce these units just with Eastern European model). Does anyone have better idea?

To sum it up:

Who exactly to ask for permission to use GREAT Cossack Cavalry textures (seem QUITE better then vanilla or I am blind)?
Who made Flemish units (apart from those that use C.A. models) and textures, who do I ask for permission to use Flemish models and do you have any idea for a single strong Flemish unit (best to make it heavy gunpowder cavalry, historic if possible)?

Did Sb2ean make all Armenian units (apart from those that use C.A. models) and textures, and do I need to ask just f Sb2ean or permission to use Armenian models and textures? (NVM about gunpowder units for now )

Thanks in advance.
