I believe you are correct. Note also the shape of the front toe and rear heal of the grip frames... XR3 are much pointier.T.A. Workman wrote: ↑Fri Apr 08, 2022 3:12 am That bottom frame looks like an XR3-RED or is it just my old eyes??

When I enlarged the photograph I wasn't able to see the XR3-RED, but do believe it is.
Also, the red and green XR3 grip frames have the large Alcoa G which means they were probably made sometime up to October 1957.
