thanks for the update:) my knowledge about these facts are a bit lacking.
The above mentioned about the armours fine details you gave, i did not know, i knew only that there were different types of armours, including different types of full plates.
About the crane stuff it aint a joke:) Even in one of Bud Spencers movies you can see it. Allthough as Respawnaholic told they were used more like for jousting. Allthough i aint sure, because i heard about very heavily armored cavalries too. Someone once told me about existing full plates over 100 pounds. [had some friends who were in this stuff:)]
Nonetheless in our land they were fast dropped, because Hungary was waging war with the turks since the end of the 14th and beginning of the 15th century, in which the turks allready introduced firearms, to their regular mercenary groups, the janichars. Therefore the heavy cavalry, which before has turned the tide of battles, was now worthless. There are countless historical records about, how our heavy cavalries suffered defeat from the turks, and how a new strategy had to be figured out:)
