Need help dating a Woolrich hunting coat

[Jack Burton]

Trying to figure out when this was made. I think they used white tags in the 80s but the style seems older than that. Thanks

, look for a WPL or RN #. If none found, the garment may be of a certain age but that does not mean the tag was not removed or lost.
Nice jacket BTW!-Dick
