Any information on pair of Heavy, large counter weight lamps w/all old slot screws

I found these today at my friend's thrift store; they were priced at $149 which is usually too much for me, but when I picked one up I was amazed at the weight - at least 20 pounds? - and the fact that all the screws - including a large one on the bottom of the base - were the older circa 1960s/1970s slot screws, and finally the control bands for the counter weight arms are wire, not cheap rubber band types.
Also the cord is a cloth? wrapped cord, but it looks so new maybe it is a replacement?
The only real worry I have is I can't find a maker's name anywhere?
Does anyone know who made these?
Their age?
Most importantly - did I do good at $150??
Thank you!

 

Forgot cord, sorry.
And a clearer photo of lamp & cord once inside - is cord original?

 

Those are some serious lamps. The plugs do not appear to be polarized, so probably original.

It seems to be based on an art deco lamp by Edouard-Wilfred Buquet, Table lamp, model EB27.

Here's a 1990s version ...

It seems unlikely that Restoration Hardware (or Technolumen) would have it manufactured with an outdated cord and plug?

HERE is an alleged original Buquet... the base is "ebonized"... though I suppose it's possible that slightly different styles were available.

Some design differences between this and the 1927 original. Here's an example from MOMA.

The cord and plug from a modern repro:

 

Mine has same large screw in bottom. That seems excessive for a copy - is mine the 1990s version?

 

1927 Vers-
Nickel Plated Brass
Ebonized Wood Base
Straight Angled Shade Arm Clamp
JMag-Do You see any small wear spots in the silver where the poss nickel (not more modern chromium) plating's worn down to the brass base metal ?

 

Where should I look?

 

Could mine have the tag under the felt like these?

The more classic lamps can go thru many iterations thru the years.I've got a Scandinavian lamp frm the 60's that's a knockoff of a late 20's-30's Bauhaus original.I love my lamp even though it's worth a tenth of the original.
I'd peel off the felt-it's like a Lottery Scratcher,hope you get a winning number !
PS-Don't forget to grab some of those used Florida lotto tickets for your second-chance prize.Everybody's a winner in the 'Sunshine State'.

 

What does the inside of the lamp head look like?

 

I sold them to a family friend for $500 but I didn't take out bulb & look - the bulb looked like small halogen bulbs?

 

JMag-Did You look under the felt for the Edouard Wilfred Buquet mark ?

 

No - I maybe should have but when I put on my FB page a friend of my dad's asked to buy them for him & his wife; their house is done in MCM (they bought a mcm chandelier from me before as well as other pieces), and since I've been buying a lot more than I've been selling lately(!) I sold them to them this morning for $500 (I paid $150 for them friday so it was less $ but very fast flip.
I believe if it turns out to have the tags he will pay me some more - again it's a family friend.

 

Cool-Some sellers like to squeeze-out every last cent,some just want to make a fair profit.I'll go back to dealers over & over again who'll work w/ me on prices.With your clients being old family friends,it's a natural move.

 

Well if you return to people you like/are fair you're more than welcome to come see me if/when your in Miami!
PS - I have some regulars who come every 2-3 weeks to see what I have new!
