I just picked up a pretty nice 44 BH (1959) and in looking it over it is cleaned up much nicer and lacks the casting marks found on my New Model S/As. Were these guns always investment castings?
Oh, it's cast all right. Ruger made his "mark" with being a leader in the investment casting of firearms "receivers".
I'm not familiar with the markings you are referring to....or are you simply looking at the "rough texture" of some of the "internal" parts? Ruger most likely reduced the "visual" appeal of the internals in the interest of cost savings.
Thankyou flatgate, yes I had removed the cylinder and noticed everything inside was finished rather well. I am starting to understand why some folks become somewhat partial to these Old Models as they are finished pretty good and operate quite smooth. I posted pics of this gun a few years back while learning more about it from the members here. I'll get pics up in a day or two. BTW this Revolver was purchased on 11/6/1959 for the sum of $72.25
