I have another question about the buttons on my military shirt. This is a korean or viet nam era surplus score. It is a very soft and sturdy fabric, not the thin green, fabric, but a thicker material, which leads me to think it is from the 50s. It has green dense plastic buttons, very plain. My question is, could these possibly be bakelite? The shirt is falling apart, and I am considering carving the buttons. Thanks, Todd
