Rocketman...Just put another log in the computer, fired right-up! Yes the"Client" was of Monumental Stature, even at the tender age if 15..see the Middle Dim, at the butt-end. In the NY times artical,3 wks ago 'All about King Michael of Romania"(Whoops.just fell to the floor,Prostrated my-self just at the mere mention of his name, just as I did acouple of weeks ago when visited by a'Purdey Owner' from Nova Scotia!!)We gunmakers who grew into the "Trade" in the reign of KING GEORGE'6'weretaught to 'Tug the Forelock' when in the presence of the 'Upper Class",,Landed Gentry..The NOBS'. I guess good manners have yet to make it up to the NE coastal area?? We, at the bench Balanced the Gun(not DB Rifles) from the Action Face,forward which usually put the POB.at the Cross-Pin,or at the lip of the Forend Knuckle. The Purdey action is Quite short,from'Standing-Breech' to TDC on B/Pin is shorter by far than a Winchester 21.So I think the POB has to be determined on a Gun by Gun basis.There are 'many' opinions on Balance, Weight Forward, for Fast Swing. less Barrel-Flip...on & on & on. As our Old Friend'The Wise-One' would say...'All Good"...He is Missed! cc
