Removing smoke smell from old radio

I got a real stinker fifty year old table radio on my hands. I've cleaned the chassis as carefully as possible, the wood both inside and out and carefully blotted the speaker cloth. When the radio arrived just putting it in a room would make it smell as if someone had lit a cigar. It's down to about 10% of the original potency and it now smells "sweet" smoky the way the air does twenty yards from a smoke shop. My question: Anyone have any favorite tricks for getting rid of that last 10% smoke smell? Or is it so deep into the wood and wires that its hopeless?
