Your brother must live in south-western Oregon.
Years ago all of the POC arrow shafts were taken from downfall. From what I was told it was all on Federal land, so no impact logging. They went in on foot cut the logs into 36" long bolts, these were then helicoptered out.
Not sure if any of this, was because of the Spotted Owl, remember that?
So alot of the cedar of yesteryear was probably first growth downfalls.
They were not allowed to cut standing live POC.
They are now, allowed to cut standing cedar, alot of it grows on private land. POC is somewhat rare.
The shafts were a tighter grain, and heavier.
I was at Rose City 8-10 years ago they were still cutting, and doweling on the same machinery that started the place.
Another thing is that they never used to kiln dry the cedar, now they are, because they are cutting live tree's.
They still make a great arrow.
