A very nice small horizontal tandem compound steam engine built by an unknown maker in 1873 and installed secondhand c1918. It ran until 1980 and was then later preserved and steamed as an outpost of the Royal Scottish Museum. It is now lying dormant in a business centre but it is still possible to see it by request. The highp ressure cylinder is closest to the camera with the low pressure closer to the crank. Both have a simple slide valve and speed control was by a belt driven Pickering governor. To the left of the high pressure cylinder are the jet condenser and horizontal air pump. I was fortunate to see this run in 1985 but haven't seen it now for quite a long time.
