Now you are testing my memory!   

I seem to remember these annotations in Wally's book, but can't, at 
the moment, remember what they mean.   The other person who is more 
likely to have a good recollection of them is John Slater, who spent 
a lot of time with Wally talking about upper partial tuning.   I 
suggest, Bill, you contact him, but I'll try and get my memory banks 
going when I have a moment to sit and reflect!
