Pea coat from a guy in New Jersey who apparently has the Aladdin's Cave of closets. Schoolboy muffler from a guy in New York who regularly finds cool clobber and sells it at a reasonable price. Filson boots that were damn near out of the box new; the owner just didn't like them and sold them to me for a song. Heavy Woolrich wool trousers, the scratchy kind, long johns required, from eBay. Underneath a Viyella shirt, also eBay and the old 60/40 cotton/wool blend, not today's wimpy 80/20.
If you bought all this gear new it would run north of a grand, easy. Cost me maybe $150 all told, and much of that was shipping.
Hat and gloves (not shown) I actually bought in a store. On sale, but in a store. Cost almost as much as everything else combined.
