9mm Concealed Trigger with a 1 1/2 inch Barrel

Both sides of the frame of this little pistol are completely covered with deep, clear engravings. The left side has the "Liege" Proof and what appears to be "1R" stamped just to the rear of the barrel junction. The engraving is not worn but the stamping is a touch light on the left side, and may actually be "JR".
