A steam engine enthusiast from Staffordshire has spent the last 30 years building miniature models of the greatest engines from the 18th Century.
Each one takes David Hulse around six thousand hours to research and build.
300 years ago the originals helped the country to manufacturing success during the Industrial Revolution, and they were all built by inventors here in the Midlands.
David Hulse says he's makes sure all his models are as accurate as possible.
He's so keen to use exaclty the same materials as the originals he converts round headed nails into square headed ones - just as the inventors would have used, and he has built a brick making machine from scratch.
His models have used 151,000 bricks in total and taken 35 years.
