'Turnierbuch - Kopie nach dem Original von Hans Burgkmair d.Ä. - BSB Cod.icon. 403' is online at BSB Munich. About half of the illustrations - modestly background cleaned - have been posted above. Dated approximately 1540. [catalogue page - I couldn't get a translation URL for reasons that escape me]
As best I can make out this paper manuscript, featuring exquisite hand-painted illustrations, is a copy after (unpublished) designs by the great Renaissance woodblock artist and painter, Hans Burgkmair the Elder, from around 1511-1520.
Burgkmair, along with Albrecht Dürer and Albrecht Altdorfer, prepared a large number of book illustration woodcuts, intended for a propaganda tribute book ('The Truimphs'), dedicated to Maximilian I. The Emperor died in 1519 and 'The Triumphs of Maximilian' wasn't published until 1526.
