Interesting question. I am not really qualified to answer, but my thinking is that Europe is a mecca for shoe making and many of them trained and apprenticed in UK or Italy. Most of them are relatively new in the trade, hence less experienced than well known houses in UK. Depending on the currency rate, for past two years, UK bespoke might be less expensive than Japanese who apprenticed (some time not so long time) there. So it can be seen "Why I pay more to the apprentice than to the master who trained him?" I am in the process of making one at GC.
