Chifferobe

I'm new here and I just have some questions. My great grandfather's farm house is scheduled to be demolished next week and I have acquired this chifferobe that belonged to him. I have searched and cant find any information about a piece like this. I have found similar pieces with square mirrors where the round one is but nothing with a round mirror. I know its is pretty rough shape and I want to restore it as best I can. I guess my questions are does anyone know anything about how old this is, where it came from or anything? And any advice on restoring it? Should I strip the finish or try to save it? I'm new to antique furniture so any help would be greatly appreciated. Thank you!
