So that definitely dates this label pre-1960 (though the absence of a wool mark already put it at pre-1964).
The example of this label Ikranieri found advertised was the
first instance she could find of it being used, which indicated this jacket could be 1959 or later. The absence of a wool mark does not rule out a post 1964 dating either. It was popular to use it around it's introduction but that has waned somewhat, although some companies still use it today, -
it is not a requirement to use the mark.
I think I have determined that Pendleton first trademarked this name in 1949 from this Trademark entry:

I see this jacket as from the 1960s/70s for a few reasons; first I have seen this pocket 'formation' on a lot of coats and jackets from the 1960's. Always that size (slightly bigger than average) that postition and often with a the pattern at 90 degrees from the main body.
Although the pointed collar was indeed around in the 40's/50's it comes around again in the 70's.
Baby blue and brown are very 60's/70's colours.
The lining fabric is also of a type I have seen and handled from late 1960's to 1970's mens jackets. It looks like acetate though you could do a burn test to find out.
Those leather? football buttons were also common on 1960's/70s jackets. (incidentally can we see the back of these?)
I believe, as a 'hand tailored' garment this could have been home made with the fabric and label purchased from a store - as such it would not have a fabric content or care label.
You can see an example of another VFG member's Pendleton jacket with a similar label (without wool mark, or R, in this case)
here that we know to be at least 1970s from the extensive material content labelling.
