Hi Folks,

If you are looking for the 504 parts manual, you can find it on-line at http://www.504.org/general_GB.htm

There are lots of pages but if you've got broadband it's not a problem - I downloaded the lot in an hour or so. The pages are well scanned and very clear.

That site (http://www.504.org/) is quite a good one if you're into 504s.
