A Raleigh bicycle of this era would have a Raleigh frame, made of Raleigh Tubing conected with Raleigh lugs, with a Raleigh bottom bracket, Raleigh cranks, Raleigh pedals, Raleigh headset, Raleigh handlebars, Raleigh stem, Raleigh seatpost, Raleigh hubs (Sturmey-Archer was a Raleigh subsidiary) and even Raleigh spokes.
All of these parts would have been made in the same factory.
The fact that Raleigh 3-speeds are made of steel shouldn't fool you into thinking that these bikes were cheap or inferior in any way..were not..were the finest utility bicycles money could buy.
Modern steel rims, cranks, etc are of low quality, because they are aimed at the cheapest possible price point.
From the mid 19th century, well into the 20th, the word "steel" was magic in Britain.
hub (c1903-1990s), it should have on the hub a date of manufacture, which would normally also be the cycle's date of manufacture. "6" for "1936." After that, they started using two-digit date stamps.
If you are not sure the rear wheel on your bike is original, the charts below should help you determine the approximate date of manufacture.
The saddles would be from Brooks, another Raleigh division, and the rims and tyres would be from Dunlop, a company closely related to Raleigh.
This level of integration has never been surpassed in the bicycle industry, though Schwinn came close in the same era.Contemporary bicycles have many parts made of aluminum (or "aluminium," if you prefer) for lightness, strength and corrosion resistance.Contemporary bicycles that have steel rims, or cranks, or handlebars, or brakes do so as a way of cutting corners and saving a little bit of money, for a low-end bicycle.Britain's rise to an industrial superpower on the crest of the Industrial Revolution was based, as much as anything else, on the steel industry and the new technologies it made possible: steel ships, steel bridges, steel buildings..steel bicycles.Raleigh originally introduced the slogan "The All Steel Bicycle" to differentiate Raleighs from competitors who used cast iron for some critical parts, a heavier and cruder technology.Actually, many well-known brands don't even do that; they order bicycle frames to be built to their specifications, with their name painted on, and equipped with parts from a variety of vendors.
