Some did have "Model of 1911A1" stamped on the slide. Others had the Norinco logo and "NP29" on the slide. Still others, especially in Canada, had distributors' names on the slide (sans Norinco).

I only regret not keeping one. They were equal to, or better than most US made 1911s, in fit, accuracy and reliability. Early ones had a phosphate-like finish, and had chrome lined barrels. Mikey D tarted up his until it was unrecognizable, and used to sing its praises to us. I wish they were available again to the US.
