Right guys here is a Spiewak B10 jacket review, Very well made, nice mouton, real alpaca lined including sleeves, I know Burt said his b15 Spiewak didn't, this does, as for fit, I take a 40 normally so this fits bigger more like a 42, it's roomier, long sleeves but then everything has long sleeves on me haha so I'm going the authentic wartime route, you get what your given and not
Jeeves and Hawkes unless tailored, I have another of these coming from Japan, a 38, if that fits me better, I may offer this one on the board first before selling out elsewhere, anyway here are pics, great looking jacket though
