I bought a pump for $2, made in China. It does not appear to be completely terrible quality. It looks just like a AFA pump, made in France, I have a white one on another bike. I googled afa pump and see https://melbournebicyclecentre.com/shop/pump-afa-plastic-black/ sell a Zefal, made in France for $10:
has the same pump for $8. it is not clear which valve fitting it comes with. They sell the little hose thingies for $3, schraeder or presta.
I searched 550A on bikeforums.net, in the last four years there have been six north Americans searching for tyres, one looking for a wheel, to suit Peugeot folding bikes, so there obviously must be a few of the in the US and Canada.
One Californian has a Raleigh Cherry:
"It is a Raleigh Cherry, 18" frame marked with "Made in England" label. Sturmey-Archer 3-speed hub stamped 81. 20" steel rims marked "Raleigh - made in France 440-20 (550A)."
Tires (original) are also made in France. "
I notice those wheels above have 36 spokes, the NS22 has 28 spokes on both wheels.
Another thing, 440-20 is 500A, not 550A as stated above, but I'll leave it here, they are French and of some interest (http://www.sheldonbrown.com/tire-sizing.html). I have not yet found another bike that uses 550A wheels.
An interesting collection of modified Raleigh Twenties can be seen here:
I told the site owner (in UK) about this blog, he tells me: "
