Noritake Morimura 1920s Teacups & saucers Incredibly Rare See Pics for explanati

Three Noritake Morimura bone China teacups and saucers. These were in a Buffet and never used. They look brand new, which is amazing for something that is over 100 years old. Please see the last picture in my batch for an explanation of the letter M on the back of the cups. These belonged to my grandmother. Insurance is required!
