B40 Bass Clarinet Mouthpiece Ligature Cap Reed Set

I am a 24-year-old female. I used this about 6 years ago.
This is a set including a silver-plated cap from Clapon, a ligature and mouthpiece from Vandoren, and reed strength 3.
The mouthpiece is B40. (Retail price: 34,650 yen)
I am unsure of the exact model numbers for the ligature and cap.
I believe each of them costs around 5,000-6,000 yen.
This is a used item, so please only purchase if you understand this.
