1930-50's brass table top or disc that is made in Hong Kong. It belonged to a lady who was 90 years old in 1978. We are not sure when she acquired it. The estimated guess is that she may have acquired it during her travel in Hong Kong in 1930 - 1950 era. Need to know the value of it. One of the websites I searched has a similar one listed as $2600. If any one of you recognize something similar, please let me know what the range of prices on this one. Thank you.
