I have one that i bought in a bunch of tooling and stuff from a friend that died in 1998 or 1999. Have modified dies and br basic brass formed- way before lapua was the king. It is a clymer reamer and says 6br-rem ai 40. The rcbs dies are stamped 83 so it was after or around that time frame- there was a ton of ackleyized stuff going back then
