Chinese Quilong mark Blue and White Porcelain Box

Chinese Quilong mark Blue and White Porcelain Box.. No damage or repair noted. I believe this box to be a Republic Era piece with an old mark reused as tribute. It is from around 1900. Measures 3 inches high by 6 wide by 4 deep.

There is some yellow staing from some very old cellophane tape that was used to hold lid on. I would think a soak in a couple denture tablets woulc disolve the yellowing. Use zoom feature on photos to see details of the pieces. Photos are an important part of the description of the piece.
