Just an FYI to this topic in regard to repairing or glueing bakelite. I have found a good way to glue this type of plastic.
I have found that using gap a zap super glue and setting it with baking soda works very well. The problem is you only get one chance to glue. The baking soda sets the glue fast so do it in a well vented area. Also no filling is usally needed and sanding a crack very smooth for painting.
