You are John Southern. As the Head of the Drawing Office at the engine workshops at Matthew Boulton's world-famous Soho Manufactory, you are one of the most important engineers in the firm of Boulton Watt & Co. You advise clients what sort of engine is best for them, and supervise the drawings from which the engines will be made. Selling the client the wrong sort of engine, or using the wrong size parts, is potentially disastrous. The future of the client's business, and the good name of Soho, rests with you.

Let's hope your engineering skills are sharp today!
