https://www.ebay.com/itm/273667385429Well-cared for Wells Gardner 19V2000 B&W monitor for Atari Asteroids, Battlezone, and Omega Race. Some screen burn-in which suggests this was used in an Atari Battlezone arcade machine. Unit has matching chassis and tube numbers, so believed to be original as-issued components. Acquired for a project that never came to pass, this unit has sat unused for about 8 years and needs to go to an appreciative home. All parts appear to be present. I do not have a suitable way to test this system so this is being sold as-is.
