There's also quite a few FEs getting around with FC mascots on their bonnets. Maybe personal preference, maybe the result of a replacement bonnet. It certainly wasn't standard practice to use leftovers as I understand it. That doesn't mean it never happened but it's more common to see FC bits and pieces appearing on the very last FEs. Graham Fuller's FE is like this - it has rubber mats in the back rather than carpet, and was like that since new. I think Cat's car might be the same.
There's a whole heap of little things deleted or changed on the FC to cut costs - GMH wanted to release the FC at the same price as the FE, so a few things were trimmed. The replacement of the bonnet button and surrounding die-cast trim with the 6 letters is one example of this. The aforementioned carpet is another, as is the deletion of boot-lining and the front number plate surround. Also the proper door-pull armrests were replaced with the much cheaper versions on the FC. They had to pay for those die-cast fins somehow!
cheers
