My .44 HE 3rd Model (W&K, delivered 1927) has posted in the past, and unfortunately it was modified and re-nickeled sometime "back in the day". I'm trying to determine when the previous owner might have had this barrel modification performed. The half-moon front sight was removed, and a checkered barrel rib with Baughman-style sight was installed. From the SCSA 4th Ed., I see that checkered barrel ribs were standard as early as 1935 (Registered Magnums), but I don't believe that the Baughman sight was around that early. It looks to me like the modification done to my .44 HE may have used a rib/sight from around 1950 or so. Any thoughts?
