No I don't. The problem is that the latching mechanism for the traverse type is unique. No other 1 e 2 GM Italian bayonet used it (all the others used the same straight slot mechanism), so the parts would likely need to come from another rare traverse bayonet. Assuming the blade and other metal parts of your bayonet are good, your best bet its to find a buggered-up traverse with the needed parts.
RE: wood. A quick look didn't turn-up any info on the wood used on the hilt. The rifles stocks themselves were maple or occasionally (not often) ash. You likely can't go wrong using maple unless someone here has exact information. The hilt rivets will be a challenge.
