On slider buttons

I have said this before but I'll say it again. Some people out there have expressed doubt as to whether the Eccleston props had such a large slider button. To these people I would like to draw their attention to the following pictures of the Eccleston era static props:

Looks familiar doesn't it? This larger button was also seen on the sliding prop also albeit sitting in a slot the width of the button itself. CO slightly tidied up the edges of this button for their toy, both protoype and production version,  but it remained virtually unchanged in dimensions and shape.

Hope this clears this up.
