Is it possible for you to publish a kind of Gamestudio Legacy Model Pack which contains the mdl files from A4-A6?

I don't know if your license agreement with the artists allows you to do so, but it would be an easy way give some models to the community.

Yes, those models are as old as the mentioned prefabs - but this would be an optional download for those who are in need of some sample models.
