Here is the actual model I did the color test for my DIY Space Marine Chapter on . It is Bruder Timo of the 6th Gruppe 4th Gefechtskompanie.

And here is some more fluff about the Chapter:

Organisation

Whilst the Codex Astartes is the baseline we compare all Chapters to, it’s undeniable that some Chapters differ in their adherence to the sacred tome. But it’s important to note that according to the Insignium Astartes sourcebook, there are several versions of the Codex. Roboute Guilliman’s writings can be interpreted in different ways.

The Galactic Knights of the Ordo Teutonicus are a chapter following the Codex Astartes but not as closely as others. The reason for this is the function the Ordo has given itself during the founding under the first Hochmeister Heinrich. As the chapter not only liberates systems and planets from the xenos but also looks after re-establishing human settlements on the liberated planets he has to guard these planets against new xenos attacks. Therefore the Ordo Teutonicus has a force called the Landwehr. It is similar to Imperial Guard Regiments, which are stationed on the systems belonging to the Ordo Teutonicus. These are equipped following the conventions of the Imperial guard. The units are named after the planets they are stationed on.

The Galactic knights consist of 10 Gefechtskompanien. Each consisting of 2 Zügen with 5 Gruppen. The Dreadnoughts and other vehicles are assigned directly to the Gefechtskompanien . This is also true for the Chapters spaceships. So every Gefechtskompanie is a self-sufficient unit and can perform the assigned tasks on their own. These Gefechtskompanien are often working together with units of the Landwehr when defending planets against the xenos. People outside the Ordo Teutonicus speculate that there might be more then 10 Gefechtskompanien as there are so many planetary systems under guard by the Ordo Teutonicus, but if that is true no one knows.

The Galactic Knights’ chapter headquarter consists of the Hochmeister (Chaptermaster), a Großspittler ( Apothecary) and a Priesterbruder ( chaplain). The Hochmeister has a bodyguard consisting of 10 space marines in Terminator armour. These are known as the Eidbrüder , as they have sworn an oath to protect the Hochmeister at all costs.

A Gefechtskompanie is lead by a Kompaniemeister or short Meister. The equivalent of a captain in other chapters. The Gefechtskompanie is devided into two Züge with 50 Space Marines each. Each Zug is let by a Hochkomtur the equivalent of a Lieutenant in the Codex Astartes. The 5 Gruppen ( Squads) in each Zug are lead by a Komtur each. In codex Astartes chapters this would be the Sergeant. The Gruppe 1-5 is in the I Zug, the Gruppe 6-10 is in the II Zug. Aditionally every company can have one additional Gruppe of 10 Novizen ( Neophytes) these can belong to either Zug and are assigned as the Kompaniemeister sees fit.
