I just bought a break open (from the bottom) 7 shot .22 short.
I see somebody else had similar dates, but it was .32
Wood grips, top of barrel reads "SMITH & WESSON , SPRINGFIELD MASS. PAT APR.3.55 JULY.5.59.DEC.18.60
SN #17692
Most of blue is gone but in very good condition otherwise and would not hesitate to shoot it.
I don't have it in my book so I do not know what it might be worth. I just liked and had to have it.
ANY HELP IS WELCOME!
