Beautiful that 3Rensho. And completely new to me.

to you maybe, the question is if it's to Nuno?

Why the lug and fillet braze? Is it a primitive form of double butting?

They're called bilaminated, they're strictly for look as they cost quite a bit, it started off as a flat piece of metal that has been carefully cut to shape, once the frame has been fillet brazed, the 'lugs' then is wrapped round the frame and brazed on (that why they look very thin), to give an illusion of an actual lugs.

so technically, they're not lugs at all, hence why it's a very expensive construction.

Look awesome though, here's other example (repost warning);

I'd guess the lugs are filed and then brazing to smooth over the top... but i didn't actually read the bit where i got it from.

More to the point has gabes polo bike been here yet?

hmmm.... ed that would be a sort of reverse bi-laminate tho, wouldn't it?

I still think it's filed and filled a bit like this:

Different method I suppose, Curt Goodrich example;

The points have been tig welded on and the weld bead was ground off. Thanks to Erik Noren for welding those on. Tig was necessary because I brazed the lugs and laid the fillets at the same time. Since fillets typically need to be done with brass it made sense to use that for the lugs too. If I had brazed the points onto the lugs beforehand with brass that filler would have melted during the construction. The melt would make the seam between the lug and the added point visible and ugly.
