In the 1980's I attended a British secondary school in Hong Kong, and in
Form 1 through Form 3 we used certain School Mathematics Project (SMP)
textbooks.  I seem to recall that the books were about A5 in size, and were
prominently labeled on the cover with "SMP" and a capital letter, from
A through H and maybe beyond, with A having the most elementary content.

I am wondering how I can obtain (used) copies of those books.  Since the
SMP seems to have long since replaced those books with newer books
that conform to current curricula, searching for the old books isn't so
trivial.  I was wondering if someone recognizes the series of books that
I'm talking about and can provide more precise bibliographic information
so that I can search for them more effectively?
