Tim, I can't recall if I looked through your Nagasawa photos when you posted 'em last year, but this year, the bottom bracket shells and lugs caught my eye. Are there any Nagasawa's with fanciful shorelines? Richard Sachs said Nagasawa "brought style and austerity to the framebuilding world," and I think it was Mark Bulgier who expanded on Sachs with, "Nagasawa's austerity: Beaucoup Bold; his style: Mos Scocious."
Below your links are some bikelist links -- tutorials -- on why frame-parts like Nagasawa's represent the best in investment cast lugsets:
