These may help...
From same wwiiaircraftperformance website:

Also:
56 Sqdn 20/07/1940 (can't vouch for the data but someone seems to have done their homework:
http://www.eskimo.com/~graham/bob/56...%207-20-40.pdf
12 of 16 Hurricanes Rotol by 20th July, 4 2-pitch.
Guess which would have been used by preference?
..6 Gloster 1st batch Hurris
built with Rotols
..'Many' (5?) Hawker 2nd batch Hurris
converted to Rotol 'by July'.
..1 Hawker third batch Hurri
built with Rotol.
Obviously some were not Rotol but it looks heavily in favour of Rotols.
