Por Homme came up with a nice find - the July issue of Journal de Nimes which is dedicated to British handcrafts. The issue features articles on Nigel Cabourn, a factory visit to Grenson and Gloverall's relationship to the duffle coat. You can view the issue or download a pdf version of it.

Nigel Cabourn is well-known in Japan but less so in the US. His label focuses on vintage and military-inspired outerwear and has amassed an impressive collection of 4,000 vintage (mostly British military and expedition) pieces. Cabourn's workshop and sample pieces can be viewed here.
