Wouldn't be surprised if the vintage material had closer ring spacing, which
is preferable.

Hi:

Does the age of the wood have any significant influence on wood
strength or flexibility?

I recently salvaged a bunch of 1950-60s 2x4 and 2x6 Doug fir. All near
clear VG. Of course they had been used for studs?!?!?

I am assuming that they were air dried due to a local mill operations
back then.
