Go to:-
http://www.metalwebnews.com/howto/bridgeport/bridgeport.html
There is a chart there. I have printed it out and put it in my
Bridgeport book.
Only problem is a lot of Bridgeports were made under license and so
far I can't find a number on these that relate to the published list.
I think there is a US and a UK list.
