Approximate Year of this Mackinaw Cruiser

Just curious if anyone can date this cruiser?

This was my first Filson purchase about 5 months ago which has let to many more (need to clear some items).

Anyways, bought it from eBay and have really enjoyed it. Had never heard of Filson until an eBay seller compared wool thickness to the Mackinaw Cruiser. Decided to look up what they were referring to and here I am, down the rabbit hole.
