Johnny,
I respectfully have to disagree with Whittmann if he states that all of them face the opposite direction.I don't have his book so I don't know how he worded it.
I have over a dozen takedowns and all of the RBNR 19's have the arrow facing the same way as the end cap. The only ones which face the opposite direction are the RBNR 20's and maker marked pieces.
