How many copies are there of Ariadne on the Panther by Johann Heinrich von Dannecker?

I do not have any idea of the total number of copies, all I can confirm that I own a copy which in total (the green marble column plus the statue) is 190 centimetres (75 inches) tall whilst the statue itself (the white marble portion) measures 80 centimetres (31 inches) from the stand portion to the top of Ariadne's head.

I inherited it many years ago (I am now 73 years old) from my grandfather James J Wardhaugh, who purchased it between 1900 and 1920 in Capetown South Africa. The story goes that this statue was not one made by Von Dannecker himself but by one of his students?

I also have a small 10.5 centimetres high, which appears to be made of porcelain but is a very damaged and badly repaired copy.

Does anyone have any further information?
