Thanks, John! Truth is - I'm moving the airplane to its new home for its new owner, and in the interim I get to toss the airplane around a bit. To my knowledge, the airplane has had it on for a number of years and the previous owner died.

You miss his point. A wheel landing in this context is on the main wheels of this tail wheel equipped aircraft. The other type of landing is a three point landing, which involves all wheels touching down together. Cheers!
