Exactly DB.
When I was involved with the artillery, they had a 32 pounder Bronze cannon cast by the Bell Foundry. It looked splendid but when it underwent its X ray scan it failed on several points that even the Proof Shop had not picked up on, and could not be fired. It ended up being one heck of a lot of money wasted for a garden ornament. Michaels idea was a nice one though!
