I have a 16Ga that I bought in Santa Barbara in 1974 that was represented to me as a Darne. I believe it is not as Darne. The only name I can find on it is on the barrel flat. I can not make out the first letter but the rest of them spell out lctifie in a half circle. In the center of the half circle is AC. It looks like a Darne with the sliding breech. Can anyone help me ID this fine shotgun? It has a one piece stock with a case colored receiver with a small amount of engraving on it.
