Need help in determining the zipper manufacturer

[Flightengineer]

Guys, on one of the G-1 I saw this replaced zipper.
The jacket of the mid-60s contract ( 7823D(WEP)) and originally it has brass Scovill zip.
And was replaced by this.





Does anyone know the manufacturer of this zipper?
Does it belong to the 60th?
I am trying to understand whether the replacement was made when the jacket was in servise or much later.
Thanks in advance.

IMHO, not original to the jacket and not military...
You can see the replacement due to the open stitching holes next to the actual stitches.
I would change it to a Scovill, Talon or Conmar ( see MASH) from the 60ies.

Hi Brice.
You read inattentively .
What you wrote I know, yes certainly I know well that these zippers were not used on contract jackets by manufacturers. I also know that this is a replacement, which I also wrote about.
My question is different.
Who is the manufacturer and what period this change can was made.

Dmitry, I checked what I could..looks as if the zipper is not from the “usual western makers”... I have a lot of stocks of old ( WW2 to the 60ies) zippers, from flea markets from Europe, USA and Korea...nothing like that ever seen.
IMHO no period replacement and most probably ex Eastern block replacement...Maybe others may chime in...?

Thank you, I've also never seen such zippers either.
I also asked this question on TFL but for now silence.
