Yeah looks like pre 60s going back to the 1920s it was sawn to 2x4 inches. There are some standards online per time range. Also found most stuff we worked on pre 50s was hardwood. Trying to cut old studs in some places was a nightmare for our blades. That or it became petrified LOL.
Fir. That old douglas fir dries hard as nails. Old barns are all nominal thickness and if you buy boards for livestock pens, they’ll all be roughcut full dimension still.
