Greg, many wooded have slight differences between the two sides due to different amounts of ‘fettling’ needed, particularly if building from hand drawn plans.
No one will be able to tell the difference anyway, & as long as each wing is outwardly the same & has the same weight then it shouldn’t make any difference to the flying characteristics.
Keep up the good work. Nearly there!

Good to hear from you, Peter, and thanks for the encouraging words. No-one else here does big gliders, so you fellows are my club.

Working very slowly on the starboard wing. Checked the L.E. aileron piece for flatness: all good. Checked the 1/8" longerons for flatness: good. Glued one to t'other: no longer flat! Guess the glue contracted unevenly... Built up to flat again with 1/16" sheet sanded to flat. This is because my first aileron works, but does not roll in the shroud quite as smoothly as I'd like. The other thing which is critical, of course, is to carve/sand the L.E.cross-section of the aileron to a perfectly straight high point. Hmmm. So I marked the center of the L.E. with the calipers and a pencil line, then stuck a piece of masking tape along the line, and checked for straightness again. Then I marked with a Sharpie along that tape, ;leaving a clear black line which must remain after shaping. Hopefully this will mean that the aileron moves smoothly and consistently around the implicit centre of the L.E.'s half-circle. We'll see whether this is enough to produce a better result than my port aileron. I've learned much about thinking ahead, and trying to understand what has to be super-accurate to produce an adequate result! Usually it means being in the right state of mind and going slowly. I can really understand now how experience with these big models would pay off over a number of builds. This first one has been one difficulty after another, even after all the great help I've had from the club (online). I think I would enjoy the next build more as well, because of the increased confidence in knowing how things are done with this type of model. My first glider, built at fourteen, was a KK Caprice, and it flew very well, until a jealous 'friend' tied the line to the towhook!
