Oh dear - I'm normally such a careful person but this time it seems that I didn't take enough pictures from the correct angle or make any notes that detail the way in which the Wave Band indicator is attached to the set - aargh!

I have two bolts with largish heads which I assume allows them to be finger tightened and each bolt has a steel washer, a spring washer and a brass nut.

Can anyone with an AC91 advise on which order these are assembled - I know that the top bolt pushes through from the back and seems to lock to the Wave Changer while the bottom bolt pushes through from the front and seems to lock to the set while allowing the Wave Changer to slide up and down.

Any advice or guidance whatsoever would be helpful.
