 No, this is not the Lorentz transform.
Lorentz used the Galilean transform first, and then he
"transform these formulae further by a change of variables".
 It's is these two transforms together that make the Lorentz transform.

 He doesn't explain the "change of variables", but the purpose is clear.
To "explain" the Michelson-Morley experiment, Maxwell's equation
must be invariant. (Idea from Poincare.) So "the change of variables"
was what they had to be to achieve that purpose.

IT COMES DIRECTLY FROM 1904 LORENTZ PAPER:
 H.A. Lorentz, Electromagnetic phenomena in a system moving with any
velocity smaller than that of light
 1904 ORIGINAL LORENTZ TRANSFORMS
 x' = β x  ;  Lorentz Eq. 4
t' = t/β - β vx/c² ;  Lorentz Eq. 5 (HERE IS LOCAL TIME WITH ETHER)
 

Quite. Directly from Lorentz.
It is the "change of variables" transform, which is not
the Lorentz transform.

Making  x = X - vt (Einstein did that, to get rid of ether)
 

No, Einstein never used the Galilean transform, but Lorentz did.
As I told you above:
Lorentz used the Galilean transform _first_, and then he
"transform these formulae further by a change of variables".
It's is these two transforms together that make the Lorentz transform:

t' = β (t - vX/c²)
x' = β (X - vt)

See:
https://paulba.no/div/LTorigin.pdf

 Einstein started with the second postulate, the speed of light
is invariant (the same in all inertial frames).
 So Einstein didn't copy anything, but since the invariance of Maxwell's
equation follows from the invariance of the speed of light,
they ended up with the same transform.

Read §3
  Theory of the Transformation of Co-ordinates and
  Times from a Stationary System to another System in
  Uniform Motion of Translation Relatively to the Former
You will NOT find the "change of variables" transform: (l set to 1)
  c²/(c²-v²) = β²         Lorentz equation (3)
  x' = βx, y'= y, z'= z   Lorentz equation (4)
  t' = t/β - βvx/c²       Lorentz equation (5)
Einstein never plagiarised Lorentz's "change of variables" transform.
and you will NOT find the Galilean transform:
x' = x - vt (or x = X - vt)
so when you said:
"In 1905, Einstein introduced (TRICK, out of the blue)
  x = X - vt, in order to get rid of ether."
you were LYING because you must know that it isn't true.

You can see what Lorentz meant by "local time" in chapter 3 here:

Quote:
"Lorentz called the t' coordinate ’local time’, as opposed to
  the t coordinate which was the ’absolute time’ inherited from Newton.
  But note that this ’local time’ is what it shown by local clocks,
  and it is the ’local time’ that can be measured.
  The ’absolute time’ t is unobservable."

I wrote: "Lorentz called the t' coordinate ’local time’"
But Richard must have read something else:

 Only a blind, deaf and stupid relativist like you deny WRITTEN HISTORY!
  Here is what Lorentz wrote about "local time" in his 1904 paper (p.813):
 ************************************
"The variabie t' may be called the "local time"; indeed, tor k = 1,
1 = 1 it becomes identical with what I have formerly understood by
this name,"

 DID YOU GET IT, IGNORANT?

Sometimes your misinterpretation of the text you are reading
is hilarious! :-D
