Hint: it may not be up the right way.
Recently I wrote a new page on earlygaelicharp.info, about possible inscriptions on the Queen Mary harp. As part of this I reviewed my photographs of the labels glued on the harp labelling some of the strings, and then I had the idea of photoshopping and cleaning up the photos, scaling them, printing them out and glueing them onto my replica in the appropriate positions.
For those of you with a Queen Mary replica who want to join in the fun, here is the image I ended up with. Print it out at 486dpi onto good old fashioned white or off-white laid paper, cut out along the black edges, and stick on using flour and water paste. The numbers go on the right hand side* of the string band (so they are visible for a left orientation player), and they are upside-down when the harp is in playing position, so the player can read the letters. They go in order, counting from the treble: 1 [illegible], 8 [c], 9 [b], 11 [G], 15 [C], 22 [C].
Any problems or questions let me know! If you send in a photo of your harp with the labels stuck on, I will feature it here!
*Right and left hand side of the harp are described as from the viewpoint of the player, not of an onlooker
