Hi, I am new to this forum and I need some info on a 38 special revolver. It is a double acton 5 shot .38 special revolver that has checkered hard wood grips and a 4" barrel. I need any info(i.e.current manfacture,framestyle size,will it accept .357 mag etc.) On the left side of the revolver it has a engraved tiger.And on the right side of the revolver it reads "I.N.A. made in brazll".And on the right side of the barrel it reads ".38 special".On both sides of the grips it reads "INA ind nac de armas brasil".On the very bottom of the grips it has the numbers "030126".And on the inside of the frame it has the numbers "575" and a 9 below the last 5. Again any info would be greatly appreciated. Thanks,Michael
