this one was my Grandpas. INA made in Brazil. thats a Tiger on this side. my Dad had one just like it with a snubnose. i got it and for some reason my sister wanted it so i got this one. they bought them at Roses for $47 each. probably in the late 50s. i know the cylinder has turned but i dont think it has ever been fired. i fired the snubnose since i was 9 till maybe 10 years ago when i swapped with her.
the first 38s are wadcutters, not semi. they punch a hole in paper like a paper cutter hole punch.
I've got a box of 1950s era .38SPL wadcutters I intend to fire through my Rossi when I finish it - I pulled one down (harder than you'd think) and the powder burned fine and the primer went pop, so I'm calling it good.
