What would be great, though perhaps not worth the time or profit, would be for some Brit. to scour the US army/navy stores for old peacoats, etc.  On the very rare occasions when I've had time to hit up a Salvation Army or Goodwill store (US equiv. of Oxfam), I usually find a few nice examples of Brooks, et al jackets that would go down fab at Simons, no doubt.  Unfortunately, few seem to be in my size.  Not only do these things still go for under $10 at the thrift shops (I'm sure less outside the big cities), but to add insult to our injury, the GBP is so strong and the dollar so weak, that it's like getting a archive of Ivy for free.
