Dining Hutch

I purchased this piece several years ago from a local antiques dealer and neither he nor I know anything about it. We have both done extensive research and are unable to find any type of information, i.e., origin, date of manufacture, style, wood type, (oak, I'm guessing) etc. I am also unsure of the style of the feet, are they bun feet, onion feet or what? The glass is original green bubble glass with leading, the top piece sits on top of the bottom piece (2 pieces), the shelf in the middle is removable and both doors on the top unit and bottom unit lock. As per the dealers wife, he broke the key off in one of the doors. A few years ago, I had an estate sale, selling my antiques collected over 25 years, but I just couldn't part with this one piece. Any information would be greatly appreciated.
