Hi
I've read both the Crowood and the Air Britain books about the DHs but I still didn't manage to understand the difference between what is often referred to as the 200-hp B.H.P. engine and the 230-hp BHP "Puma", maybe because they are sometimes both often referred to as the "B.H.P".
Was the second a completely different engine?Or was it an evolution of the first which was re-named for the occasion?
Of course confusion reaches the top when one reads that *both the Galloway Adriatic and the Siddeley Puma
were often referred to as the BHP Puma, although they were different and not inter-changeable engines.

Thanks in advance.
