Hozaabout a picture of the threaded end of the barrel extension? BA experimented with the a method of cutting the threads by broaching that left a square notch running longitudinally with the threads. Got a drawing of it but never have seen one.

On the barrel extension: I have a drawing from BA showing cutting the threads by broaching which leaves a cut or groove running longitudinally with the barrel threads. Apparently, BA sent this to RIA as an alternate method of cutting the threads, RIA filed the drawing with the rest of the barrel ext. drawings, however nothing further has been found on this subject and I have no idea if this method was ever adopted.
