The topic of the thread is Winchester Shotgun Barrel Steels William. The thread is factual and well researched, with obvious gaps in our knowledge; knowledge unrelated to having worked in a steel mill.
So do you have an opinion as to the composition of Winchester Nickel Steel? Winchester Stainless Steel? The Stainless Steels available in 1926? Or is this of no interest to you?
BTW: Researcher has documented that the $750 Remington Special Hammerless Model of 1894 was offered with barrels of Nickel Steel. Interested now?
