The gun in question is listed in Brophy as a first series momogram grade. It has 30inch Whitworth barrels, a Hunter one trigger, and looks to be identical to the A3 grade gun shown on the dust cover of Brophy. I have known of this gun for about 40 years. It letters in Cody as a monogram. If it is an upgrade it is a darn good one. I suppose one way to settle things would be to remove the lock plates and look for a grade marking but the gentleman who owns the gun doesn't want to do that for fear of damaging the stock. There are no cracks in the stock anywhere. The gun is in excellent condition.
