New Without Tags Black Sheep Sport Coat.  Fine herringbone texture in the weave.  This is a sample jacket which I bought from Brooks Brothers, no brand labels.  Light padding in shoulders. Two Button, Double Vent.  My guess from the construction details is that this was manufactured in Thailand.  My guess is that this is made of wool and some smaller percentage of silk, just my guess.  40R.  Measures P2P 21.25, Sh 18 3/8, Sl 25 7/8, L 28.25. 

I combine shipping.
