Operating Manuals & Related Materials

On this page are scans of some operating manuals and leaflets. If you have any more from Bell Punch and Anita I would be delighted to receive a copy for display here - please get in touch with me.

Sometimes, with Internet Explorer version 6 each page is shrunk to fit the window, making reading difficult. To see the page at full size and scroll around, hover the mouse cursor over the image until the expand/contract button appears at bottom right, and then click on it. A similar feature may be available with other browsers.
