The 50 courses (in 10 parts) are the reverse of Lates' peal of 1842 (Stedman 1903 edition p.129). 
The basic block shown there was HLQ,HL,SL,HL,H. 
Lates put the other 10 courses between two 'Doubles'.
This was the first peal in the method to reduce the non-bob calls to just one pair. 

The original peal was rung at Aston in 1842 and gave rise to
almost endless controversy as to whether it was by Lates or
Thurstans - both were trying to produce a peal with 'ordinary'
calls and the minimum number of singles. The credit for
reducing the number of singles from 22 to 6 in Hudson's similar
peal was Thurstans', but the credit for reducing this to two
by the use of 'Extras' and 'Omits' was certainly Lates'.
  
Had Lates realized that the two 'doubles' he used could be
replaced by two ordinary singles, his peal and not the 1846
Thurstans Four Part would probably be the famous one.
