This is a vintage handmade woman's wool jacket made in the popular Pendleton 49er jacket style. Every pattern company had their own version of this jacket in the 1950s- this would have been sewn from one, and maybe even using genuine Pendleton fabric!
 
This Pendleton jacket clone is a brown wool with a very subtle woven check. Almost a color-shift fabric, I see blue in the fabric depending on how it's hit by the light.  The unlined jacket has the requisite large pointed collar, cotton-lined back yoke, patch pockets at the front hips, button front with large shell or abalone buttons, and cuffed sleeves. 
 
Pre-owned, this is a genuine home sewn vintage jacket from the 50s. When I found the jacket it had been munched by moths, leaving tiny holes in several places. Because I LOVE mending vintage clothing and making it wearable again, I decided to mend the jacket with a series of small wool patches and/or darning with wool thread. I kept the patches and mends subtle but refused to hide them entirely. The sleeve patch is a piece of wool from a Pendleton shadow plaid shirt that was damaged beyond repair- I love how it's plaid fits so well with the small checked weave of the Pendleton clone jacket. 
 
Just as an extra FYI- the two large buttons on the sleeve cuffs have also been replaced with shell buttons from the same era. AND I should mention the discoloration under the collar at the back of the neck. No idea why it would have happened- it's the only area like this.
 
Handmade, there's no size label. Shown on my size S mannequin. I'm guessing it should fit a modern size M woman but please read the actual garment measurements given next--
