It seems more likely that there was no h1 or any other h in this
word (*artros > L artus). Since Latin had r-r > r-0 dissim., the rule
never took place (ev. that it's only cases of XtR not Xt that caused
aspir. in L & G, and after PIE times).

Even if there had been another "laryngeal", why no tH>T>f>v>b in
Latin? It seems likely there wouldn't have been any reason for
analogy here. The only odd thing is the loss of r, thus indicating
that that is the necessary condition for the rule.
