Our local charity was given a very nice antique walnut sideboard / breakfront

We’ve been told that it’s circa 1830’s Massachusetts and was shipped around Cape Horn to Longview Washington in the 1920’s by one of Longview’s founding families. We need to sell this piece so that the proceeds can go to our charity.

We’re asking for any help that might assist us. Attached are photos. More photos in higher resolution are available.

Any information or corrections to what we’ve called it or what we think it is would be helpful. We don’t have photos of the back or any detailed photos of the inside but if that would help, we can certainly provide that.
