Is it my geezer memory or is this an unusual expander plug for an RCBS 38/357 die set? Set dates from 82, I bought it with a bunch of other dead guy stuff.
Picture did not come out clear enough, it appears to be able to have a decapping pin mounted on the expander.
I have since peddled it, I don't need 3 sets of 38 dies when I don't even own a 38. Yet.
Just curious.
Thanks,
