This perversely unknown type caused a sensation when it was discovered during a stocktake at the Science Museum of Victoria in the 1970s. The two known examples are believed to be from the former property of H.M. Le Souef, the late Deputy Master of the Melbourne Mint who left much of his collection to the museum.
