Hi guys, these are (just for a change) GB Dark Ages Infantry, with West Wind heads in a few cases, painted up for Dux Brit (but probably equally suitable for other Dark Ages games
).
My experience of the hand replacement (spear hand for sling hand) was that it was quick and easy. Since the hands are small and very light, I've found the butt joint with cyanoacrylate was plenty strong enough, without the need for drilling and pinning.
