It needs to be remembered that when the performance figures are expressed
say at max 130 mph that usually means when the aircraft is new and running
well. Most aircraft especially in ww1 would not be able to go the max speed
as they got damaged, worn out, maintainance not up to scatch etc. It might
be said that the Camel went 120 but in reality it was more like 110 or even
less.

I always thought the Sopwith Camel was pretty fast; 130 mph or so, as
well as
maneuverable. It's generally considered the best Allied fighter of WWI
(I think), although Spad and SE5a have their adherents.
I'll try to look up some numbers tonight (JM Bruce _War Planes of the
First World War_ or the Profile series may cover this), but my memory
of various references matches the comments from "Winged Victory". The
numbers I have in memory for Camels are around 120 mph at sea level,
the SE5a was around 130 to 135 mph at sea level. The Camel
performance was supposed to fall off more rapidly with height. I
recall comments which seemed to be more specifically `Clerget Camels'
suggesting that this may not hold for the BR1 engined Camels (or less
so). It is probably true that variations in engine output and
reliability was greater in WW1 than in WW2 due to lower metallurgical
and other quality control, which would further complicate matters. It
is recorded that in December 1917 the British had around 400 SE5a
airframes awaiting engines, the quality of many of the supplied
engines not being acceptable.
In 1918 the two Australian squadrons (AFC squadron #2 with SE5a and #4
with Camels if I recall correctly, don't remember the RFC/RAF numbers)
were operated together with the SE5a's used for top cover and the
Camels for low level. When the Camels were replaced with Snipes this
tended to be reversed, suggesting that Snipes had a better altitude
performance.
