...when the factory moved to Westfield around 1,094,000.
That serial would be 1965. I've heard nothing to indicate that the factory didn't move in 1960. I would say there might have been a lot of Chicopee barrels in inventory when they moved.
Since you can't tell the style of thread while the barrel is attached to the action I have collected little info on the subject. I don't remember anyone finding a Chicopee barrel with "V" threads but not sure.
I see in the data that there are Chicopee and Westfield barrels in 1961,1962and 1963. Square or "V" I don't know.
Are the threads per inch the same on both thread styles?
