38 Military & Police (postwar).
Serial numbers ran from S811120 in 1945 to S999999 in 1948.
Yours looks to be about a $300 gun tops.
It was a Performance Center 6" 686 in SS. The only info I still have is its Serial No. which was BHN96##.
Serial dates to 1991/92.
S&W offered at least eight different six inch barreled 6 shot 686's thru the Performance Center. One of them was a "carry comp" as well as the "competitor", "target", "hunter", etc.
