Today I went to the Museum of Power in Langford with some friends on a photowalk. There were vintage cars, motorbikes and traction engines on show as well as the usual static steam engine exhibits. I got talking to David, who was there showing his hand-built miniature traction engine, McGrew. He took five years to build it from scaled down plans and regularly takes it to steam fairs and country shows. David was very enthusiastic about his machine and quite happy to chat. Thanks for your time David, it was a pleasure talking to you.
