Dating national guard jacket

[Altomarevintage]

Was wondering if there is a definitive way to date national guard jackets like this 

[BEAST]

Researching the unit (using both online and books) to find photos/descriptions and then looking at the details of the jacket. Are the seams and button holes machine sewn or hand sewn? Check the manufacturer of the buttons to help narrow down the date.  Post details and ask questions here.  Good luck!

Thanks so much. I can’t tell how these were soon lol

Can you take a clear photo of the buttons front?

The back should have a maker like Beast mentioned. Might narrow down the State.

 

The one looks like an eagle ????

and the other look.like a monogram.  Maybe it looks like letters?? Possible clue.

 

Cool looking jacket!

its  NY national Guard. i think the one button was a replacement.

I meant Date not State. On my phone!!!

So no maker on the back of buttons?

You can look up button makers business and get a possible date from when they existed?

 

Just a thought.
