Button shawl: http://www.stevenalan.com/BUTTON-SHAWL/62454,default,pd.html not sure who else has themProbably wouldn't hurt to contact EG about the buttons, they're usually good about helping out with issues like this.
It has raglan sleeves, which probably accounts for a long sleeve measurement depending on where you're looking.Jack Straw in Seattle had several in various sizes when I was last in a week ago, though I can't say for sure if a medium was still available. Have you called them yet to check?So far there's also an upland vest and button shawl.
Jack Straw got a in few things:
QT vests in a few different fabrics
U neck knit vest in navy wool
Primaloft down vests in green ripstop
Cambridge pants in grey herringbone
Odin has some things online as well: http://www.odinnewyork.com/search.asp?Mode=Type&TypeID=18
Amazing price. It's just waxed cotton with some lining around the shoulder area (no warmth) and it's definitely a shell piece to layer on other things. I had to rewax some seams on mine, but it's otherwise performed great in Pacific Northwest weather.
