Thanks! I think our friend got his companies mixed up! I have several Preco nozzles under various names...Singer, Westinghouse, Beam come to hand. Primitive but effective. Later ones had a plastic neck instead of metal and are prone to cracking. Greg
Gary!
Rainbow offered the Preco as an accessory for the chrome dome. It was offered at $19.95 us. They claim it spun at 4500 rpm! And it was just called the power brush. Greg
I remember that Rainbow did offer the Preco. When I was a kid my aunt called my mom over to see her new Rainbow D and of course I tagged along. She had purchased the optional Preco with the Rainbow. It also had a plastic telescoping wand.
