I am looking for originals full suits of armour from Netherlands from the second-half of the 15th Century, such as Memling was painting. I know a lot of armours from other European countries, but no like such.

Unfortunately not much extant armour from this period remains here, so full suits are especially out of the question. There are some effigies which have survived the iconoclasm, I believe there's one in breda if my memory serves me right.
When aiming for a low countries impression we'll have to base our impressions on artwork, unfortunately.

Yes, full suits are pretty much out, but parts do exist, and there are some very fine effigies, as well as the paintings; we used to call Memling 'the man who thought he was a camera'.

On the subject on Memling, I came across this rather nice armour close-up in a triptych by him.
