I had a friend who had a death in the family recently, she was cleaning out her grandmothers house and came across 2 revolvers, she had no idea her grandmother even had these guns, she gave them to me to see if i could find any info on them and i figured i would check here before google.
First question there is a small P one with a triangle around it on the front of the trigger guard and one to the rear of the trigger guard without the triangle, what do these emblems mean? ( see pictures)

Second question anyone have any. Idea on value of this revolver i found online anywhere from $900-350.

Any help or advice would be greatly appreciated
