Need Help Identifying and Dating Vintage Pendleton Hunting Jacket

I have a vintage red / black Pendleton Hunting jacket.

- four pockets with metal snaps on the front. Pockets are square to the bottom of the jacket and not angled.
- hunting pocket across the back accessible by snap flaps on either side
- six button design (no Pendleton on the buttons)
- Tag has WOOLMARK logo indicating mid 60's?
- Tag indicates size M -- although it fits truer to a L.

Please see attached photos.

So am I correct in describing this as a vintage Pendleton Hunting Coat in a Black and Red Tartan Colorway from the mid'60's?

Thank you in advance for any information.
