Is there any pic of a Bristol Bulldog powered by RR Falcon?
No, because by the time the Bulldog was designed the Falcon was nearing the
end of production.
The two original Bristol proposals to F.9/26 were for aircraft powered by the R-R F.XI
and Bristol Mercury. The latter led to a Jupiter powered private venture that became
the Bulldog. While originally listed as a Falcon development the R-R F.XI was a very
different beast and was renamed Kestrel.

K3183 was used as a testbed for both the Napier Rapier I and the Alvis
Leonides.
