What to look for is always the same: The extra tubing (which then also leads to longer valves because they have to support two runs of tubing going through them).
As a simplistic approach, if you can follow the tubing through the valve section and each of the tuning circuits and out the bell, and then there's a bunch of tubing "left over" that takes a second run through the valves, then it's compensating. Or if you start to follow the tubing from the lead pipe, through the valves and through each tuning slide, but you get confused about which branch to follow at some point, then it's compensating.
