I don’t have too many early Nieuport engine numbers but N16 serials 5171,5172 and 5173 (ex RNAS 9154, 9155 and 9158) had 110hp LR numbers 2742,2733 and 2730 respectively.
I have most of the Morane LR engine numbers and a few are in the range indicated above:
80hp LR 2925 was in A186
80hp LR 2926 was in 5150
80hp LR 2969 was in 5194
80hp LR 2970 was in A176
