You can use less drastic methods by just immersing the whole plane in vinegar or citric acid overnight to remove rust. The weak acids won’t harm the rosewood handles and will free up loose bolts and nuts. It will turn the brown rust ( Fe2 O3) to a black film (Fe3 O4) which comes off easily.
Then rinse the parts with water and a little detergent to wash off the acid ( add a little baking soda if you wish ) and clean the parts up with a metal polish like Autosol of Maas to get rise of the black.
