ABC V 2 on Auction

Hello, I saw this motorcycle at an auction in Italy that ended on December 5th, 2024 (auction house ``ASTE BOLAFFI``), lot number 63, the motorcycle was sold. My question: Does anyone know this type ABC with a V 2 engine? So far I only knew the type with a boxer engine, does anyone know more about it? Regards Wolfgang

I think its home made with a Swiss engine, https://www.astebolaffi.it/en/lot/156/63/detail#gallery-8
