"A-yu-shi with Lance and helmet", Guiseppe Castiglione, 18th century. If that sounds like a not so Chiense name it's because he was a Jesuit missionary who ended up also working as a painter for the Qing court.

And there's the image limit. A full zip archive of this and the images that there wasn't room for (next to nothing in the way of arms and armour, but a decent bit of jade and other treasures): https://www.mediafire.com/file/rvmr5uqyknmgti9/Taiwan_-_National_Palace_Musuem.zip/file

Well, the book I just posted is a lot older at least (1630, whereas Guiseppe there only showed up in Chian in 1715, meaning the painting can't be older than that). I didn't pay a lot of attention to paintings without any military connection, so I'm not sure what the oldest they had around might be.
