Thanks for the links and suggestions above, I will get the above mentioned Source book for some rough OOBs.
As I have seen the books by Pat McGill? (only found this name in the preface at the Vexilla site) 'Standards, Badges & Livery Colours' and 'Heraldic Banners of the Wars of the Roses' mentioned a few times and they seem very interesting.
But the preface of the 'Heraldic Banners of the Wars of the Roses' made me curious how the list cites it sources. Are there any mentions of the sources where the banners are drawn from or is it a list wargamers have concluded to compromise with in terms of research effort and historical accuracy? I know that this is a hobby after all but as one can easily access a lot of primary sources online this would be great to cross check the banners.
And following on this, is there any book that lists the miniatures in
'Sir Thomas Holme's Book' or is there maybe even an edition of the whole thing? Some names can be read pretty easily put other are harder and without proper knowledge of the nobility of the time I think this will only lead to utter nonsense.
Same question goes for a version of the
Grünenberg Armorial, while this one is not WotR specific I guess there are is some useful heraldry hidden in these.
