Audi 200 quattro Trans-Am

In the descriptions of chassis number TA/3 accompanying the history of the 200 Trans-Am, it's stated that the car ran only in the last race of the season (St Petersburg), driven by Rohrl, and is owned by Audi Tradition. However, in Racing Sportscars's history of the cars, [url]https://www.racingsportscars.com/type/archive/Audi/200%20quattro.html[/url], TA/3 is listed as having been driven by Haywood in 13 races, wearing number 44. The site also states that Rohrl drove either TA/2 or TA/4 at St.Petersburg, both of which had appeared at other races in the series during the season, driven by either Rohrl or Stuck. Also, an article appearing in Audi Club North America's website announced that the Haywood car, presumably TA/3, is owned by United Autosports and would be appearing at the 2018 Monterey Car Week.

TA/4 was offered for sale by Canepa of California in 2018, after spells in South Africa and in private ownership in California. So my question is; which chassis is the car owned by Audi Tradition? Can anyone shed any light on this, please?
