I had the pleasure of tying next to John Mclain of feathersMC at the mason fly tying show. His seal fur is very very nice. The source for his supply is pre-ban. AS I understand it , some enterprising soul discovered that wold army surplus winter coats from I believe he said france, had seal fur in the liner as the filler material. So someone bought all of these coats from the surplus that he could, cleaned the seal and dyed it.
