Hello
Speaking of possible 5040s of Cabot, Brunel or Birmingham Carter,  I
said "At the Triples stage, if the building material is to be sixties
of either Carter or Stedman Doubles then the only hopeful one is
Birmingham Carters but with bobs in lieu of each 7ths place (to give
60s of Carter Doubles)"

In my other ramblings I had hoped to imply that in Caters or in
Cinques, in my opinion, to get a true 5000, one could choose to have
bob be n-1 instead of at any one n; or instead of any two ns or
instead of at all three ns
Having n-1 at only one n keeps the 12 rows as a unit and is obviously
the better choice if ease of calling is the prime consideration

Referring to Birmingham Carter Triples the website statement that

"This principle, which is actually an extension of `Reverse Carter
Doubles', was rung in Birmingham in the 1980s using two different
calling positions within a lead." is wrong. To get a true 5040 of
Birmingham Carter Triples it appears to me to require all three
calling positions in the block of 12 rows. In fact, Alan Burbage
certainly did  not use only "two different calling positions within a
lead" he found it necessary to use all three.

Speaking of Alan Burbage and the 5040 of what was to become known as
'Birmingham Carter Triples :
John McDonald (p244 RW March b14 1980) wrote:
"His analysis showed that it is necessary to use all the potential bob
positions in order to obtain the full peal. The bob positions are all
those occasions when 7ths place  is made. ie at the first row of every
six and at the 4th row of every Carter six. As in the case  of Stedman
, the bobs require 5ths place instead of 7ths. In fact, in Alan's
composition,a bob made at the first row of a Carter six is invariably
followed by a bob at the fourth row of a Carter six."
