I just purchased this coat with a wonderfully subtle windowpane weave in nubby light blue on grey and I’m wondering if it’s more 1950s or 1960s. The union label inside is the one used from 1949-1962 but is it possible to further narrow down a date? The raglan sleeves are what’s throwing me off because most overcoats I’ve seen from the 1950s have set-in sleeves. Any help would be appreciated!
