Vintage Antonelli felted single button swing coat with snakeskin trim

Vintage burgundy/purple single button swing coat with snakeskin print trim at neck. Wool, polyamide and mohair blend fabric, exclusive of trim. I am not certain of the trim material. Some of the trim has detached as shown. Two slash hand pockets. I believe this to date from 1979 based on the tag code. Italian size 42 I believe corresponds with a US size medium but please see photos for measurements.
