Wally,
Well I assume you have not picked up your latest copy of the SAAC registry yet. For a bit of lighter reading, there is some good information on the recent history of "AC" in Trevor Legate's book "Cobra The First 40 Years".
I guess with the limited information from accars.co.uk website, your summary reads information between the lines that is a bit inaccurate. Angliss did not sell the company to Lubinsky. The banks took over AC. The banks sold a portion of "AC" to Lubinsky.
Nothing on the site you mentioned states there was only 1 CSX1000 supplied by Lubinsky. It appears that he supplied at least CSX1000 thru CSX1014 before he was unable to deliver more cars and Shelby sued him.
You may want to take a look at this thread:
Aluminum Body
There are some pictures of CSX1021 there, which Shelby apparently sourced from
North Devon Metalcraft | Manufacturers of replacement steel and aluminium motor bodies
