Your pictures didn’t post.

That's kind of neat, whatever the heck it is. Has it been painted brown? It looks like a nice grain to the unpainted surfaces.

It doesn't work as a dry sink--looks like all 4 sides are finished and it's not meant to be against a wall. Could it be a sewing box and the towel bars are just handles?

I agree that it looks like a sewing box. The bars on the sides may be to attach things that someone is working on such as when hand weaving or types of lacework.

May be a wash stand?

Probably not a sewing box.... those have a lot more drawers/cubbies/trays to accommodate sewing notions.

A wash stand would make sense.

It was probably originally lined and possibly had trays. Sort of like this, but probably older:

I think it's a made-up piece. The leg/handle are components from a pump organ.

I agree likely a made up piece.....but weren't most things unless they were factory pieces? Which this definitely isn't....but I don't see any pump organ in this one?

HERE is an example of a pump organ. Good spot by Sombreuil.

I have seen that design or ones similar to that on the sides of various cabinets so it is not specific to organs. From pump organ comment my mind went to a foot peddle.

I think this is where Sombreuil owes us his organ photo.

I think that the nails we see are not original, but were part of a patch-up made after this piece had aged. The drawers may have been glued together, and then came apart. The owner resorted to nailing to keep it together. Look at the 11th photo. Toe nailing was done with nails that were much too long and the nails protrude by a large amount. This is sloppy patching, but typical of someone using whatever he has in his nail bin. In earlier photos of the drawers, the nails are not evenly spaced indicating these were placed by eye, and not measured.

some of the assemblages for mounting the handles extended far up & down the sides of the case, and were screwed on from behind.

There were 268 brands of American reed organs, and each brand had countless case styles, the odds of me finding one that looks exactly like the example are nil, But just so you understand I wasn't hallucinating.
