This requires a quick pass from Google Translate. But this is a complete list of blazons from the Gelre Armorial! GOLD MINE!
The blazons may be a bit modern, since they were added later - but this is still a goldmine of emblazons to look over.

Johann Siebmacher's Wappenbuch from 1605
It's all in Dutch(?), but the images are fantastic!
"This month our featured item is a manuscript containing over 1200 hand-drawn, coloured illustrations of coats of arms. They represent nearly 600 years of history, from the reign of William I, King of England (1027/8-1087) to the reign of Charles I, King of England, Scotland and Ireland (1600-1649). Although the author is currently unknown and the accuracy of some of the representations is doubtful, it is an interesting work which usefully demonstrates some aspects of heraldry."
