Which Arne?  

In the furnitureindex it's at...
In the furnitureindex it's attributed to Arne Vodder.
Which source does it attribute to Arne Wahl Iversen?

There are a good 20 or more attributions on the net
I was surprised by the quantity so wanted to double-check, as we all know that many of these sources can be unreliable (inc DFI)

Well, the one and only...
Well, the one and only reliable source doesn't exist, at least on the net, even DFI is sometimes wrong, but in this particular case you can be sure it's designed by Arne Vodder.
No label on it?

Yes
Here you go:

The stamp shows Vinde Møbelfabrik, but Vodder didn't work for Vinde, but Arne Wahl Iversen well.
So we have a perfect confusion. 🙂

Povl Dinesen catalog has...
Povl Dinesen catalog has this listed as Iversen...but pulls seems to be slightly different

Thanks, Jesgord
It's very similar, but as you pointed out the handles are different

here's another variation I found
with squarer legs

As previously noted
furnitureindex.dk is a good online reference, but not 100% correct. Every time I check it, I look to see what their own sources are. In this case, Los Angeles Modern Auctions is the source.
I put greater stock for IDs on old catalog references over auction references any day. Then again, I am of the opinion that there is no Poul Jensen individual (even though he is credited with design of the Z chair), but rather Selig marketing in the US mistook that name for an individual rather than a furniture manufacturer that made the chair.
P.S. I own this entry chest/planter, and am in the Wahl Iversen designer camp.

I will look through my Anton...
I will look through my Anton Dam, illums bolighus and John Stuart catalogs tonight and see what else I can turn up

Are we all in agreement that the stamp
Is for Vinde, and not Vamo Mobelfabrik?
If this is the case then I suspect that it's less likely to be a Vodder design.

It's definitely the Vinde stamp.

Does anybody know the maker of the square legged variant? I've just picked on up, there are no stamps on it. And can't find one bit of info!

Based on the fact that the legs and stretches are Afrormosia, it was not made by Vinde or Vamo.
