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)
