Outlet vintage sterling heart brooch with arrow and book locket

i've seen these little book lockets before, but not set within a heart. a sweet brooch that could be personalized on those little book pages. marked sterling, locket closes nicely. a few small scratches on the surface.

height: 1 and 9/16"
width: 1 and 1/2"
height of heart: outlet a bit over 1 and 3/16"
