Canadian Mk 11 Churchill Tank

[chris vowles]

Can anyone help?

Near where I live in Worthing, England we have a rusting Canadian Mk11 Churchill tank. http://www.findonvillage.com/0959_mo...r_downland.htm

Known as the "Dead Heads" this one was left to the Canadians to use as target practise. It has lots of bullet hole all down one side.
What I would like to know is what sort of gun would have been used to make these holes all the way clean through 70mm plate on the side of the tank.

I have been told Piat or Boy's but I don't, to the best of my limited knowledge think that they would have gone right through.

Have attached photo, I hope.
