Presumably whoever does buy it will have to spend the same sort of money again
getting it zero timed, it cannot fly as it is without a CofA.

We locate the odd bearing for vintage aircraft restorers, many of which
are old surplus stock well out of grease life and with no paperwork. I'm
told these can be accepted as the aircraft are operated under a CAA
'permit to fly' rather than full certificate of airworthiness. I presume
this arrangement would equally relax the requirements for an engine. I
still don't imagine it would be a trivial or inexpensive matter to
recommission such a thing, but perhaps not quite as daunting as it might
BTW. I believe the Merlin 134 is a bit specialised being fitted only to
D-H Sea Hornet - don't know if it's the left or right hand rotation one
Turning to "British Piston Aero-engines and Their Aircraft" (Alec
Lumsden, Airlife Publishing, 1994) it seems the mark 134 was the RH
rotation version. It was manufactured c.1950 specifically for the
Hornet/ Sea Hornet. The 130-135 series Merlins for the Hornet had a
variety of differences from the usual Merlins such as reversed coolant
flow, down-draught air intake and a more streamlined profile.
I wonder what "Brand new condition" actually means. The engine in the
photographs seems to be partly dismantled.
I reckon he's found it in a crate & took the lids off for a looksee before
actually believing his good fortune! I'd have thought the BoB F would have
grabbed it if it could be flown in one of their aircraft.
The 'permit to fly' scheme is administered by the Popular Flying
Association. (now called the Light Aircraft Association) I was one of their
inspectors a few years ago.
P to F aircraft eligibility was controlled and mainly concerned homebuilt
aircraft, limitations on weight and engine power also apply, it was about
200BHP IIRC - clearly a Merlin wouldn't qualify! The warbirds come under the
wing of the CAA and 'special category' certificates of airworthiness.
One of the problems associated with an engine like this on the e-bay could
be a lack paperwork for traceability of components - it could prove very
troublesome convincing the CAA that the engine is fit for flight, even after
I suspect it'll end up in a tractor pull machine :-(
It was up there a week ago, same price, and didn't sell.
The bloke down past Weston way has shedfuls of the things. Merlins
aren't that uncommon. AFAIK, this is 20k of engine tops, as it's in need
of overhaul and isn't a popular mark. Amongst the three or four racing
warbird engine shops in Leftpondia, there's still a good trade in the
