OK, catching up on some more research I started well over a decade ago on the founders markings inside the OM XR3 and XR3-RED grip frames.
Looks like two different markings exist for the XR3 and there are three different types of XR3-RED grip frame, important stuff to know for originality if somebody tries improving their gun with a better condition grip frame.
XR3:
1. "ALCOA" with large "G" December 1953 to at least 5/22/57 (ship date).
2. "ALCOA" with small "G" 10/8/57 through the rest of XR3.
XR3-RED:
1. "ALCOA G" 7/31/62 to at least 2/4/65
2. "ALCOA G2" with solid grip dowel 2/15/67 to at least 6/3/71
3. DJ in a circle with roll pin grip dowel From at least 6/24/71 to end of OM
I'm not sure on this but think the rollpin was changed from the solid pin concurrently with the change to the DJ marked frames. DJ - Doehler Jarvis
If anybody can improve the ship dates of these varieties, please let me know. Am especially interested in knowing what that two year period on the XR3-RED grip frames look like between Feb. '65 and Feb '67.
