Lundstrom La Parka 100% wool, vintage coat

Vintage coat, great condition. Minor small stain on front left side of jacket. Detachable hood. About knee length. No size tag but would be about an XL. I am unsure what the symbols mean unfortunately! From what I understand, this was a sample jacket made (that’s why there is no outer shell) and it was from Linda Lundstrom‘s family member.
