Top is a late 80's KR637. 33" wide, 18" deep ~19" tall. Value, IDK, what are they asking for it? I'd say maybe $200-250, for one that is in good used condition. Meaning no rust, straight, no large dings, all drawers work properly, needs nothing mechanical, maybe just a good cleaning. If it does need work or parts start going down from that. I could see a really nice one going for maybe $300+, but your average used one less. I have the same box, but it needed quite a bit of work and I lucked into a good deal on it.
I wouldn't discredit the bottom box right off the bat. It could be a decent vintage box, yea maybe it isn't a top of the line SO from the era, but I'm sure it is a pretty good box.
