Bad decision, not the same
This is a very bad decision. In the case of "okidataparts.com", the trademark name was used in conjunction with a generic term, the end result being a generic term -- "Oki Data Parts". The name does not imply that Oki Data operates or authorizes the site in question. In this case, however, "ITT Barton" was the name of the company making the products (the name of the company was then changed to "Barton Instrument Systems LLC", and they've since been acquired by another company). They may have had a trademark on "ITT" only, but "ITT Barton" was the name of the company. As such, this reseller's domain "ittbarton.com" is very likely to be assumed by purchasers to be the official and/or authorized domain for the company's products.
If the reseller had called his domain "ittsurplus.com", "ittbartonsurplus.com", or something similar, then it would be acceptable. But to use the defunct company's name as your domain name is not something that should be allowed.
Here's a question for the "good decision / common sense" commenters -- do you think it would be acceptable for a person to purchase surplus Digital Equipment Corp (DEC) computers, then register the dec.com domain name to resell those DEC computers (yes, I know HP controls the domain name, but assume for the purpose of this hypothetical question that they didn't)?
