Hey Jamey.... Gonna be tough. Was the "piece of wire" the other missing ring? It would probably be like a tough puzzle. Each piece would have to go back into its original position. And I assume the wood is all dried out. This meaning you can't swell it back up. Now if you'd just like it "back together" and not hold water then some good wood glue, pin stapler and some time would all work out. Clean ring, prime and paint and just slip back on with a few short screws. Good luck buddy!!!!!
