There are still a couple of dingbats from my previous post that are proving tricky, and I would also value your input on the others below.
1) a3 (the 3 is shown like a cubed symbol)
2) 11>2THE (the 2 is crossed through with a back-slash and the word THE has a white horizontal line through the middle)
3) The number 7 underneath a horizontal line, with the word TON reading upwards from the line
4) EPO H
5) a line of music notes, grouped into threes and shown as triplets (with the number 3 above each group of three notes). There is no indication if it is the treble or bass clef, so they could be 'g' or 'b' notes.
6) R U (the U is on the far right of the box) ... could this be as simple as 'are you right'?
