[Healeys] 100 Service Manual trivia query

[Peter Svilans]

Yes, the books and sales sheets always began with just the number, with "A"
added for the first upgrade. Sort of like what we would call the 'second
floor' of a building being called the 'first floor' in England.

Curiously, my 997C is dated September 1956, but I have a 97H997D as well,
which is ALSO dated September 1956. My BN2 Supplement 997/ I  (March 1956) is
inserted loose, unlike Mike's.

Another 97H997D which I have has dropped the large month and year on the title
page, but says "copyright BMC 1959" in fine print at the bottom, so the "D"
must have been the last 100 Service Manual which was reprinted multiple
times.

These three-digit numbers were in-house publication numbers, and the "97H" was
later added (in Sept '56 ?) to make them official Part Numbers and the manuals
could then be ordered over the counter.

The 100-Six Service Manuals carried right on from the Hundreds, with 97H1489
(May '57) covering the BN4, and "Issue 2" of the same number adding the BN6 as
well.

Later the numbering system was overhauled and the 97H numbers became AKD
numbers.
