Answers.Body: <p>The set that had the most pneumatic cylinders was the Lego Technic Backhoe, with something around 10. Unfortunately, this set is discontinued. You can, however, buy it on <a href="http://www.bricklink.com/search.asp?itemID=38937" rel="noreferrer">Bricklink</a>.</p>

Answers.Body: <p>In the UK shop, there are currently two sets:</p>
  
  <p>The <a href="http://shop.lego.com/en-GB/Mercedes-Benz-Unimog-U-400-8110" rel="noreferrer">Unimog U 400</a> [set:8110] which uses the motorised "compressor" to supply the power (as opposed to the manual sprung pump).</p>
  
  <p><img src="https://i.sstatic.net/Osl4J.png" alt="Detail of pneumatic elements"></p>
  
  <p>And the <a href="http://shop.lego.com/en-GB/Tractor-with-Log-Loader-8049" rel="noreferrer">Tractor with Log Loader</a> [set:8049] which uses the manual pump:</p>
  
  <p><img src="https://i.sstatic.net/cY7NN.png" alt="Log Loader detail"></p>
  
  <p>The other sets that look like they have piston arms (such as [set:8043]) are actually using "<a href="http://en.wikipedia.org/wiki/Linear_actuator" rel="noreferrer">linear actuators</a>", which work with an internal screw thread to lift up the piston, powered by Bevel Gears or Universal Joints:</p>

  <p>[part:61927c01]</p>
  
  <p>These provide a much finer level of control over the Pneumatic sets, which is probably why they are being used in more and more sets.</p>
  
  <p>The issue with locating the pneumatic sets is that there have been a few subtle changes to the elements over the years, as well as different lengths in various sets, so tracking them reliably isn't easy:</p>
