Ok, here is my 500 point historic Teutonic list (not including leaders), 30 BGs in total. This is to represent a large "field" army of the Teutonic Order like that fielded in the early 1400s. For a "Grunwald 1410" battle you could add more "guests" while lowerign the numbers of prussian troops.
For a late 1300s army, you could add more witings and one more guest, while removing the bombards and mercenaries.

Notes -
A) It is unclear how large percentage of the infantry were "townfolk" and how many were rural levies. As I said before, the Order was a centralized bureucracy. Its lands were mostly forests, swamps but also some very big and rich cities. Therefore I assumed that out of the "commoner" infantry 6 would be townsfolk, 2 would be rural pesants, 2 would be Witings (rural prussian style infantry).
B) Rossdienst and "Guests" are the same stat-wise. They respresent wealthy large landowning nobles.
C) Prussian horsemen are represented as protected cavalry, but this is my own view. If one wants, they could be seen as protected or unprotected light horse archers, as we really have no sources specifying how these people were armed.
D) Rural foot spearmen are medium foot with ligth spears, not "Defensive spearmen". This is to express the fact taht unlike town levies, they probably did not receive "goverment issue" weaponry. Therefore they might also be depicted as unprotected or even mob if you wish, however definitally not "defensive spearmen" like the printed book says.
E) "Platendienst" are depicted as armored knights (because they are nobles, just poor ones), but if one wants they could be "downgraded" to armored or even protected cavalry. Sources say that they had "light" armor, but this can be understood as "light in comparison with brother knights or rich landowners" and this is how I see it.
Where has the info come from, if you don't mind me asking?
Mostly from Nowak&Stolarczyk "O wojskach Zakonu Szpitala Najświętszej Marii Panny Domu Niemieckiego w Jerozolimie zwanego krzyżackim" (eng: "On the military of the Order of Brothers of the German House of Saint Mary in Jerusalem, also known as Krzyżacy"). He gives most details, including the description of the weapon&armor stockpiles, as well as the Rossdienst, Platendienst etc. conscription laws.
Some general social info (social classess, rough percentage etc) from Gerard Labuda's "Dzieje Zakonu Krzyżackiego w Prusach"
Some info also from Stefan Kuczyński's "Bitwa pod Grunwaldem" and "Wielka wojna z Zakonem Krzyżackim w latach 1409–1411".
English-language sources are few and most are not that good from what I heard (usually taking Dlugosz's anti-Teutonic XV century propaganda as fact). In general, most in-depth sources are in Polish or German.
