Drexel Heritage?? China Cabinet and Buffet Cart??

These pieces of furniture was given to me by a friend who is in the miltary and was stationed over seas and couldn't take with her. Beautiful pieces of furniture I tried to compare it with some pics of china cabniets online the closest pic I found to was Drexel Hertiage manufacturer?? I have looked everywhere on the chinia cabniet and Buffet cart but can not locate manufacture. I need to sell both the cabniet and buffet cart   b/c I have no room for it but can not locate the manufacture to value the furniture. I do know that it was passed down to my friend from her grandmother who is from Italy so not sure if the furniture is from Italy or not. So I plan on selling both pcs as a set. So if someone could let me know any info on theses pcs of furniture I would be grateful even a value as a set or seperate and what would be better value to sell as set or seperate 

Thank You
