In 1988 the boys at the Graz, Austria Landzughaus took out some original arms from the armoury there, incuding a wheellock pistol and carbine. Among the tests they conducted was to see if they could pierce an original breastplate from 1570 or so. They both managed to cleanly pierce the breastplate. The pistol was shot from something like 8 meters, the carbine from somewhat further away. But what is interesting with the pistol is although the breastplate was punched through, the linen on the other side DID stop the ball. :shocking: Interesting!
Anyway, most of the decent armour was, as noted above, "proved" or proof-tested prior to planishing and issue/sales. Sometimes the "proof" was done with a ball-peen hammer of course, but usually it was legit. The armour with MORE than one dent in it was definitely battle-tested though!
Thanks for posting those pictures. Cool stuff!
