Tibetan 19th century 7-pronged vajra bell

Tibet Made of bronze alloy. 7-strand diamond bell. Era: 19th century. This is a century-old bell. I bought it from a fellow antique dealer in Taiwan in 2024. At that time, I bought a magic weapon worth 110,000 yuan. This bell is one of them. Most Tibetan bells and pestles have five or nine prongs. This bell has 7 strands... Strange shape. Never seen it before... 7-Eyed Dzi Beads... The industry says it represents Medicine Buddha... 7-pronged bell and pestle... Could it be a bell and pestle made specifically for practicing Medicine Buddha Dharma?? Can't determine the exact age... I tend to underestimate the year first. It is believed to be a second-hand item from the last 40-50 years... I have been searching online for months... I just found the same model in mainland China. The original era was the end of the Qing Dynasty. Basically it has a history of a hundred years. The seller of this broken bell on the other side of the strait offers NT$3,200... 6800-114.05.01
