No Roadster lugs are available for the independent or small shop.
That is why I had to make them.
Roadster lugs are made [India, China, Taiwan and of course in the Netherlands], it is just that distributors like Nova and Ceeway do not buy them.
I find it amusing about the comment about TIG welding lugs.
Why lug anything really...
it is just for looks.
Stamped lugs are welded together :) Only the expensive racing lugs are cast.
I think you best bet is to try and find them in India or Taiwan and ask for a sample.

If by "roadster geometry" you mean a slack (66-68 degree)
head tube and seat tube angle
I think you might be out of luck for anything commercially produced.
The cost of creating a wide variety of investment castings and distributing the product is high and the demand is minuscule.
You might look into TIG-welded custom lugs, such as those made by ANT bikes or by Mark Nobilette as described in Bicycle Quarterly vol.

This ANT-built bike appears to be an example of a roadster geometry frame using custom lugs.
Most of the examples of bicycles I've seen in this style appear to have just very simple tubular lugs rather than anything particularly fancy.

The best place I've found is Henry James Bicycle supply .
They make frame building jigs, and supply most boutique US based frame builders.
Ceeway is a good choice in Europe.
Some lugs may need to be custom cast, or modified, depending on the head tube and seat tube angles you choose.
The fork rake will need to be fairly slack to match that style.

Nova Cycle Supply offers many framebuilding components including lugs.
I can't speak to geometries.

The title says it all. I want to build my own frame and need lugs that will fit the roadster (e.g. Raleigh Tourist) geometry.
Where can I buy lugs for a classic roadster frame geometry?

Roadster lugs are not available to individuals or small shops. They are made in India, China, Taiwan and the Netherlands. Distributors do not buy them.  However, it appears they are available at Nova Cycle Supply, Ceeway and Henry James Bicycle supply. Perhaps the best way to get them is find a seller in India or Taiwan and ask for a sample. An alternative is to use very simple tubular lugs.  Some commenters say that Nova and Ceeway stock lugs, while others suggest that they are usually not made to order and can only be sourced from the manufacturers in Asia or the Netherlands. ANT Bikes, Mark Nobilette and Henry James Bicycle Supply are also good suppliers, but custom casting or modification may be necessary.
