I have an Eibar copy of a S&W DA revolver. I don't have any pictures and I'm at work but I recall it says something on the barrel like "use best quality Smith and Wesson .38 cartidges only". Obviously an attempt to connect this pistol with a genuine S&W. The SN is:E30495. It's was my grandfathers. It's reasonably tight and I've shot it a few times.
