Coat 70's cream trimmed sleeve front buckles Abbott zipper old?

Lovely vintage coat. Looks like 70's to me. No tag. Measurements are in description. Trimmed around the collar, the sleeves, around the bottom of the coat, and down the front on either side of the zipper. 4 buckles, metal clasps. Lined inside. 2pockets. Dry clean pile fabric method only. No issues, just needs to be dry cleaned. I don't know what type of fabric or trim. The measurements are from shoulder to shoulder is 17". Under the armpit to other side is 18". From shoulder to bottom of sleeve is 22". From shoulder to bottom hem is 32". Around the waist is 16" across. I measured at the 3rd belt. Suck a timeless classic! Please let me know if anyone has any information!!
