WE must be careful with PO Ackley marked rifles.I have one in 338-06 AI that I know for certain was only barreled by him. The person I traded for it from did the rest of the work, using a Herter rosewood stock.Unless there is more than barrel markings, especially if the stock work seems a little "off",it should be suspect. Of course if it comes with invoices,letters,etc from Ackley;the matter would be clear. The current owner may be completely innocent in his belief that it was made by Ackley.
