Hand Carved Wooden Angel Statue

This is a priceless piece to me, but I'm wondering if anyone would actually know what its worth. I hear all the time that I should get it appraised.

My grandparents story goes: My grandmother was volunteering to help build a church while my grandfather was stationed in the Phillipines during the Korean war (he was in the airforce). The priest, as a gift for her work, gave her this angel (there's a matching one that her friend received possibly) from the old church. My grandparents kept it on their covered porch, where it withstood years of weather.

Its amazing up close. The paint is peeling, and I'm not sure if that is original? The wood, especially the face and wings, is so detailed with the carving. There are no markings that I see to identify an artist.

Does anyone have any suggestions on how to find out a history on this piece? I believe its old, but could it be from 500 years ago?

Its incredibly sentimental to me as it was my grandmother's, but is the story I've heard possible?

Thanks in advance!
