Vintage MAH JONG GAME SET WITH CASE good

Product Name: Vintage MAH JONG GAME SET WITH CASE good
I Apologize, Although I do my best to research everything extensively, this was confusing and difficult,  I thought this was a complete set and was mistaken. I apologize for this. This game has been in a closet for a long time. I believe it is complete 143 tiles 3blanks. I have no idea good how to play and the instructions somehow were lost. The tiles are pure white and show no age, I believe that they are Bakelite as they have no seams and doesn't feel like plastic. One corner of the case has been repaired and is barely noticeable. Please see pictures as a more accurate description of condition TY.
