From what I’ve read ambrotypes weren’t really invented until about 1854 and lost popularity in the early 1860s, so you can reduce your time period by a few years that way.  Generally I avoid tinkering with old, delicate photos like yours for fear of inadvertently damaging them, and rely on research for the most accurate dating.
