D Cells, (or the British equivalent) C Cells would look pretty tiny hanging off of Mr. Prowse's backside. ;)

My scale must be off then. You're right, those must be bigger than I thought, Mr. Prowse is a tall bloke.

As an aside, I'm surprised they still make C cells. There don't seem to be many gadgets or toys that use them today. (AA's or smaller are dominant.)

We have a Kienzle wall clock from the mid 80's in our kitchen and it's the only thing in the house that uses a C cell. :)

I have an old handheld electronic game from the 80's that requires two C's plus a nine volt!

I hate to go off-topic, but may I ask what is it? (reply via pm if you so prefer)

This one.

It made for a great "flashing computer console" prop in one of my college video projects many years ago. I lost the decals and other pieces over time though.

To steer things back on topic, I also have this little beauty...

It uses six(!) AA's, but I eventually found an AC adapter for it. Much to my surprise, one of the Rebel Assault games used the sounds it made. Nice little obscure reference.
