Upgraded Wood?

[J.B. Books]

Hard to tell, I think I can see a hint of the gold shield and looks to be almost exactly midway between the end of the pistol grip cap and the dhpb which is kind of odd to me.

If you lift the trigger guard, be very careful. If it has been in place for a few decades, or more, you can very easily damage the wood. Go slow and easy. I learned many lessons over the years, and trigger guards was one of them! Good luck!
