Thanks Ed.

I thought of that, but again, it depends how you hold the pistol to view the barrel and/or frame.

If I hold each revolver in my right hand and flip from the barrel view to the frame view, the IDs are "*9" and "69 H" respectively. That what appears to be most logical. I will go with that unless there is better answer.

I thought maybe there was a standard position for viewing these numbers.

FYI, the ID is on the left side of Model 2 frame and on the right side of the Model 1 frame.
