Can you identify these 3 tables?

Extremely rare early Finn Juhl set for Baker Furniture - get them quick!!

Formica tops?
Skip it, they don't look like anything special to me. I see these type of tables at the thrift stores once in awhile. Unless you're in need of a table, that is vintage.

Hope springs eternal.
Handy rule-of-thumb, Dashes:
Wood furniture is good.
Formica furniture is sometimes good.
Formica printed with a faux wood grain is never good.

I believe they are Heywood Wakefield
I may be optimistic, although not nearly as much so as Paulanna.
Formica/laminate does have it's place though. I wouldn't have to worry about water stains.
But what about HW making teak items? I thought most of their stuff was birch or something like that.

Further reflection upon formica
If faux-grained formica is atop particle board, then it says to me: I want to be real wood and I want to make others think that I'm real wood, but alas, I'm not.
But faux-grained formica atop actual wood says to me: I wish I trusted you enough to not have to cover myself up this way, but I just know you are going to eventually put a wet glass down on me, and I just don't want us both to suffer the consequences. So, I'm doing this for both of our sake's. And I'm adding the grain just to remind you that there actually *IS* real wood under here.
Perhaps I shouldn't be listening to furniture.

Well. . .
I'll buy your distinction. But how often do you find laminate on solid wood ? I agree it would be far superior to a lesser substrate -- remembering always that to remain warp-free the bottom face needs to be laminated too.
Now what are these tables, really. . .? Did Heywood Wakefield really do "Danish" ?

I only have circumstantial evidence to support my belief
But it's pretty strong.
The other day I found 3 items in a local thrift store: a MCM desk and 2 side tables, just like those 3 pictured. The tables were marked with a number and just the word "teak" on the underside. The desk also had a number and "teak" on the back, BUT, inside of one of the drawers was also marked with the Haywood-Wakefield mark. They all had the identical laminate tops.
Here's the kicker: inside the drawer was also a Gideon's Bible. LOL... Clearly, a local hotel/motel is redecorating (or, more likely, going out of business).
Heywood-Wakefield apparently did a lot of contract manufacturing.

Heywood Wakefield had several ...
Heywood Wakefield had several lines of Danish Modern furniture starting in the mid to late 50s and continuing well through the 60s. The "Teak" stamp refers to the stain color (just like Wheat and Champagne).

A shit piece of furniture by...
A shit piece of furniture by a good maker is still a shit piece of furniture

True --
but nothing about these, even the laminate (if that's what it is) necessarily makes them "shit" -- from what I have seen so far. The identical materials can be used well or poorly. . .
I don't personally react well the the exaggerated curvature of that top stretcher -- we've seen this several times recently -- but the forms of these tables still seem well-wrought to me. Just because these may have no provenance doesn't negate their possible good qualities -- in my opinion !

When I wrote that faux-wood Formica
"is never good", it was in reference to the original question of identification.
What's the point of "identifying" vintage furniture, unless it appears to be a worthy, superlative example? The fact that these tabletops are made of wood-grain Formica should tell you, at a glance, that they're low to medium quality, mass-produced tables.
After making that determination, knowing WHO designed and manufactured them is superfluous information.
I'm not trying to talk you out of owning wood-grained Formica, buy whatever appeals to you. But, investing time in research of such stuff is senseless, isn't it?

WHC - I couldn't agree more....
WHC - I couldn't agree more. I'm sticking to my considered critical assessment - they're shit. And I mean 'shit' in the wholly pejorative sense should there be any misunderstanding. Maybe its my internet browser at fault but I can't see the banner that says "DesignAddict Forum - Please place links to shit you've seen on Ebay and Craigslist here". I'll try Firefox.

Perspective
Taken from the perspective of trying to understand and identify the various items from a particular manufacturer (in this case, Heywood-Wakefield), the quality was not the primary issue, it was the MCM design.

Quality of material
tends to mirror quality of design.
