This is in excellent condition, and measures the wingspan 1 5/8" wide.  The wings have tiny springs on the underside to make the wings move as shown.  This is marked on the underside with hallmark that looks like LOU 750, but I could not figure the maker so if anyone does know, I'd love to hear from you.  This weighs total including the stones 10 grams.   Please look closely at my photos for details.  Item 4470
