[r-t] ringing-theory Digest, Vol 184, Issue 1

Mon Jun 8 06:32:28 BST 2020

There is three lead splice between London Surprise and York Surprise :

(3 in-course leads) x5xx6 of London <----------> (3 out of course leads)
 xx56x  of York.

There was a 720 in Composition 500  or 501, I think.

The same type of splice works with Kent and Oxford Treble Bob, where the
methods are 1 lead splices.

There is also a type of 6 lead splice where 6 leads of Cambridge Minor
correspond to 6 Leads of Double Bob Minor and 6 out of course leads of
Double Oxford Minor, with the same pivot bell in each.
