The axe in my picture has stamped on there that it is made in the UK.
Though the response was not wide my impression is there is consensus on how to distinguish left from right side, which is pretty interesting.
In fact, I wonder if even the double-bitted has left and right distinctions given that a lot seem to sharpen the two bits in separate ways.
Over usage is a different matter then, right. Sticking to the rule, it doesn't matter which side is flat and which is beveled on side axes there is still an unchanging right and left side. Only after that is it a question of which one is beveled or flat. I am left handed, I want the flat on the right side of the axe, when I lay it down there, the cutting edge points left, and the work to my right, my right hand up high and left hand down low. This stance will allow me to maintain a posture at relatively right angles to the work, otherwise you get a bit skewed all around. I really like to do hewing, very satisfying work.
