These are good photos, but there is another great set at http://timster1973.wordpress.com/2012/11/09/the-lost-alfas/ who says there are only 6 cars.
The original source website is dead. Well, it might just be having issues, but it doesn't seem to work. http://www.28dayslater.co.uk/ and so I learned about this on http://sucksqueezebangblow-juice.blogspot.com.br who posted it a month ago
A couple photos are at http://www.wernerschijvenaars.nl/gallery/71988 but they aren't as good as these ones, and provide no info
