OK I understand, I'm afraid I don't have a more detailed picture, it was scanned from G. C. Stones' "Glossary...", which is why the quality isn't great. All I can do is link you to a slightly bigger scan:

About those Japanese laminated gauntlets, I have seen Turkish and Iranian armours with laminated vambraces that extended down to the knuckles. Unfortunately the only picture I have of one these, is a rather poor quality picture from Robinson's "Oriental Armour" of a 15th century Turkish armour, now in the Metropolitan Museum in New York.
It has to be said though these laminated vambraces look suspiciously like greaves. I saw this armour in the Met about four years ago, it has now been placed on an equestrian figure, and the vambraces are no longer there.
A reconstruction of this armour is also on the front cover of an Osprey Men-At-Arms book:
