Here is somewhat of a sad story. Back in February of this year a group of artifacts from a relatively famous sengoku period samurai started popping up for sale on Yahoo, local auctions etc. I did what I could to get a hold of the armor pieces as I knew they had significance because they belonged to a huge guy. Around 2m in height huge. All of the items had the same family crest on them in the form of a gilt coppery brass kanamono that was a very unique christian kamon. VERY sadly, the dou which originally was decked out with these decorative mons all over had been vandalized by a faker who wanted to put them on a composite armor composed of some original pieces and this fake helmet. That way if they all had the antiqu mons on them it would look like a non-composite armor. But it was done at the expense of an important christian daimyo's armor. Just another reason you should support properly trained restorers.
