Indeed, the current
HH arms are a pertty good fit scale wise, hands are much smaller though. Could even end up looking better than originals
When I originally compared the new
HH plastic beakie to the previous
FW resin model, I concluded that indeed torso was identically sized on both models. Hands were smaller, legs were more legit looking anatomically (longer legs as well), heads are a touch smaller.
HH backoacks are chunkier than old ones, and a tad biggger. You should certainly try how the new
HH heads and hands would look on vintage sculpts!
You could also use modern pauldrons methinks
