Can anyone identify these pieces? It is from the 1800's. It has been in our family for generations. Not a clue where to research it. Thank you. It was my grandmothers aunt who first bought it in the 1800's she died in 1880. Then it was passed on to family members up to now. The inside of the neck looks like there is a gold bar in side
