Here's the URL for my Hobbs of Barbican website which contains some history, catalogue scans and photographs of a few choice machines:
http://freespace.virgin.net/
I'm hoping to add more stuff to it in the coming months so if you've anything that would fit in, please let me know. In particular, I'd love a scan of the Hobbs downtube script as a replacement for the title on each page.
Thanks to Bob Reid for putting the website together and the VCC's Mervyn Cook who supplied much of the information.
Cheers,
Bruce
