Wild assed guess here- I think you MAY have an EM-GE "Valor" revolver. They were made as blank pistols for 8mm blanks, some were "modified" to fire .32 S&W. No rifling in bore. PLEASE have a smith check it over before shooting anything but cap pistol caps in it. Do not want to hurt anyone's feelings, and I am really not a gun snob, but value on revolvers like that are about $25.
What we have here is... failure- to communicate.
