Yes, I agree. Should be 620/621. Also, middle bridge is similar to the 131. I have one in the boneyard, took detailed pics 2 years ago of the dial side & dial but neglected to take the obvious pic of the bridges. When I find again, I’ll share, but it too is from before cal # was stamped on the plate.
Unique that it’s Gruen w co (not WSC) and—on this one specifically—the sn appears to line up with the V4 / non-precision (at this time) series. Well, possibly. Contrast vs. cal 615, which is Gruen w co and even Precision, but has a non-Gruen sn.
