Elisabeth Gaunt, the daughter of Barnes Wallis, says she is condemning the sale of fake items marketed as the marbles that inspired Wallis’s “bouncing bomb.” She has spoken about her decision to sell marbles she associates with her father’s work after learning from auctioneers that the items could be valued at around £250,000. According to the accounts provided, the discussion centers on the authenticity of products being offered to buyers and the potential for misleading claims that the fakes are genuine. The reports frame the marbles as part of the inspiration for Wallis’s weapon used in the 1943 RAF raid, often referred to in connection with the “bouncing bomb” concept. Overall, the coverage focuses on Gaunt’s reaction to collectors and sellers promoting items she considers not genuine, while also noting that authentic marbles tied to her father’s legacy attract high interest at auction.
