I know, I know, this is a 1911 forum, but . . . . . . I happened across an old S&W revolver that I am being told doesn't fit the normal S&W model designation. I am interested to know if I have a unicorn, a "Wednesday after mardi-gras" production piece, or a "one-horned goat." For starters, it is a Model 36 "no dash". Anyone know more than the average bear about these?
