I hope that someone out there can help me. As I am about to approach manufacturers with my invention, I need to find sales figures from other suppliers of similar goods, but am having problems knowing where to look. Does anyone know where I can get hold of sales figures for an American firm who supplies Safety Siren radon detectors?
