How old do you want it to be?
About 235 years would be nice... When I get the bottom out I am hoping to find a tin type of George Washington resting his foot on it while signing the Declaration of Independence
LOL - No made in China sticker. No marks at all with exception of a few pencil lines if memory serves. I haven't a clue as to the inlay. Definitely wood but just don't know. It's the nails that confused me a bit but maybe they are made to be lower profile since they are on the top. Less to cover.
Chinese makes sense given it's origin and the popularity of Asian item in this area.
It is a neat chest. Regardless of age, by the time we are finished with it, it will be well on it's way to being an antique...
