Default Identity of Prop (boss)

Good evening all,
A visitor to the Irish Air Corps Museum and Heritage Centre showed us details of a boss which he has (it always makes me sad when the propeller is cut to the boss) It has listed the following on the side :
27.5 Rolls Royce (or it may be 275)
D280, P3600, AB 686 RH and with 2751 on the front.
Any help is much appreciated.
