Vintage silverplated "2 Fingers" Jigger by Napier.  Vintage barware, measures up to 2 oz for a double shot.  Nice condition - there are some dark spots at the bottom corners, I can't say for sure if they'll polish out but I think they will.  Marked Napier on the bottom.  Next time someone asks for "2 fingers" of liquor you can set this in front of them!
