I have no idea how it was used or cleaned. I either bought it at a show in PA years ago from a woman who was selling her husbands guns and other stuff.
I have the original receipt indicating it was bought from ASHLAND SHOOTING SUPPLIES DISTRIBUTORS, Ashland, Ohio March 4, 1981by a gentleman in Ohio who's name I will not publish here.
Seems to be in nice shape and was not abused. I never shot it.
FYI: It sold for $245.72, tax $13.51 (5.5%) and $4.00 shipping.
