Antique Display Case

I inherited a good number of antique items and am currently in the process of figuring out their value. This is a display case in near-perfect condition. It is currently being used to hold a 54 piece set of Royal Copenhagen - Blue Fluted Full Lace china. Being that is a very high end fine china set, I have a good feeling the quality of the display case in question possibly matches the quality of the china. I have not been able to locate a makers mark but am not comfortable in trying to move the case to check on the back. Thank you in advance!
