Teak room divider help?  

Here is the Spivack mark. It doesn't really tell us anything, though, I don't think!

Leif,
The drawer construction on many of the Randers Credenzas are very similar. We know Leo imported from Randers but that's another far fetched attribution.

Is the drawer construction similar or identical? Because the drawer construction across basically all of Scandinavia is on a continuum of similarity (same for the USA), so it is identical that really starts counting for something.
This is a tangent, but why not?: I have a Kai Kristiansen for Aksel Kjersgaard vanity with triptych mirror, and the inset circle drawer pulls. From the 1960s. Aksel Kjersgaard currently makes a Nissen & Gehl desk, and the website has a photo of the side of the drawer. Identical construction to 50 years ago and across designers. A shop decides on how to make a drawer, and it is amazing how it sticks.

If I had a Raneders credenza in front of me I could tell you with confidence: Identical or Similar. Unfortunately I do not 🙁

What, you don't have a extensive stock of Danish prices catalogued by maker, designer, and with multiple specimens per design showing variation across time? 😉
I call it similiar. Very close, but still similiar.

It looks like the teak cap on the top edge of the drawer face is thicker on the Randers. Good thing, too. Mine has several veneer chips on that piece!

Yeah the veneer band along that edge is not very common. Most were a bit more generous there.
