George: saw your post March 1 on the LCSCA Forum and if those fellas don't have an educated guess, you're probably not going to get one

I didn't want to embarass myself over there, and hate to say this, but if your gun was made after the first floor of the old Hunter Arms factory collapsed Jan 16, 1949, guns in process or on order were completed with components on hand, and you may have gotten a Field brl. Is it marked Armor, London, Crown, or Nitro Steel? Nitro was used on Specialty grades, Armor on Fields. You can find pics on p. 401 of John Houchins' new book.
