I don't have the inclination for another hobby, but it would be interesting to compile a list of where the British name their bicycles, and their cars, after their aircraft. They certainly "recycle" the names. Or... just a coincidence?

Thank you for that prompt
I already knew the story behind the Holdsworth 'Sirocco' name but while finding a reference I found this:
https://www.classiclightweights.co.u...hirlwind-1952/
It's 'well known' these days that the wind is actually spelled 'scirocco' but apparently Holdsworth didn't know that and named it 'sirocco'
and renamed it the next year as 'whirlwind'.
The reference says 1952 Sirocco with
Stronglight 49D with 46/36 TA Cyclotourist rings
Campagnolo Gran Sport rear
French Cyclo front
regina 14-16-18-21-24 freewheel.
.
So that's a 1952 10 speed Whirlwind with Cyclo FD + 49D/TA and 5 speed on the back.
