Sorry on the typpo...It is a .38 s&w cal. That IS a lanyard. The grip logo and frame stamp looks like it DOE'S say AHC .
I found MANY old revolvers that once belonged to my great,great uncle. My father had them wrapped in old rags in the attic. This (and a simmaler looking H&R were the best. Asside from a "LARGE" flair gun,) and my Grandfathers w.w.I helmet.
