VINTAGE BUTTERKNIFE SET W/CASE BONE LIKE HANDLES

This is a set of 13 vintage butter knives with a velvet lined case. The handles may or may not be bone. I don’t know. The knives have numerous stamps some apparently in Arabic. I received this set from my grandmother who is now deceased but was from Paris, France. She traveled extensively throughout the Middle East. Some handles are damaged and cracked. Look good at photo’s please.
