Found in parts, put back together. no idea where from...

So I found 'it' in quite a few pieces, it seems like it was handmade. It was also put back together once before, when someone introduced screws to it.(bummer) Has quite a few through tenons, that are not machine cut. It is fairly light weight, was stained, not sure if when made or when it was badly rebuilt before. Not sure if those are makers marks in the forth photo, I have found them on four different places.
