No, no eMail problem
I was just trying to get answers to (any of) your questions - but I haven't been able to find that damn booklet. It may have been one of the Gakkens - or maybe not - and I remember the other sections were translated into English - just not this one.
I am going to have to locate this thing, to tell you any of what you need to know, or to order the work. So just stand by, for what/when I can tell you.
