Whilst this is a photo copy, and some of the pages are a little askew, it was all readable and intact. A real bonus finding an old manual for a classic piece of kit that no other site had.
It was easy done, and I got exactly what I was looking for.
Text excerpt from page 9 (click to view)
The grill pan is supplied with a removable handle. To attach the handle, place the wirework under the cut out in the pan so that the metal plate hooks over the top of the grill pan. Slide the handle to the left and over the central bump on the grill pan.
Ensure the handle is correctly located. It is not necessary to remove the grill pan handle during grilling.
Place the grill pan on the shelf so that the pan is positioned centrally beneath the grill.
To remove the handle, slide the handle to the right and lift the handle away from the cut out on the grill pan. Note If you require an additional handle for your grill pan, this can be ordered from Parkinson Cowan by quoting part number 311479800\6.
