Top pics there sarnie!
Peter M will be quite excited by the one at the bottom no doubt!
Yes, I think this thread will take some researching!
Like you I thought I had a reasonable idea a few years ago about a few of the cars but now i'm not sure.
For example we know who drove some of the cars originally but what we don't know is their original identity.
What we need is people like Ric, Brian, Dave Streather and co to get wind of this and post some ideas!
If we can get enough info the thread can go into the Chassi numbers forum!
