Sierra/Wall Street II and the CSUSA Apprentice Classica- can anyone provide a definitive answer on if these two models use the same tube? I know a number of the Sierra clones use an identical tube, but there are a few that don't.......... I do know they use the same published drill size, but given the amount of slop gluing up tubes in the sierra when using the 27/64", it wouldn't surprise me to find the Classica uses a slightly larger tube. Any help would be appreciated!
