Hi there, looking to find a 9220n. This is a black dial camaro with 45min register without tachymeter. 9220nt and 7743n models seem quite common, but so far I've only seen one 9220n for sale at a Bonhams auction last year. Here's a link to it on the Heuer Camaro page: https://www.heuercamaro.com/models/9220/9220-n Let me know if you see one! Cheers.
