Walt,

From the info I have, it looks like most of the SE5s used by RFC Training squadrons (both the RAF and Training Command were a bit down the pike yet) were pretty much standard PC10. Most used for training did not mount the Lewis gun on the top wing.

There were some night fighter squadrons that had muted checkerboard schemes. Check the Windsock Datafile book. It's a good one. Available through Hannan's Runway.
