Not to derail the thread, but the original rendition on Frazetta's The Silver Warrior was
a Dragontooth set from '78 (which I once owned, but foolishly gave to a girl in the early 80s). So rare I can't even find any pictures of it, fully assembled.
At close to the same time (but slightly later, iirc) is
the Ral Partha version. Also a very lovely figure. Rare and hard to find.

I've been meaning to try and scratchbuild one, but if some clearly talented sculptor were to set his mind (and tools) to the task, I would jump on one (or three) of them. (hint, hint)
Ideally with a sled more like the Dragontooth version.
