Hi Bill: Unlike the OT, where many different code cylinders were used, all of the non-saga officers have consistently used one single type of code cylinder (the blue-tipped dosimeter style), so that's the only one offered for this CRL, until new officers are seen with different types of code cylinders.
The vast majority of officers in the OT used the same sort of code cylinder, except with a brass clip, while the non-saga officers used silver clips. The silver clips are required for higher level approvals, but we've allowed the brass clips at the basic level, so people with pre-existing code cylinders (of the correct type) don't have to replace the clips unless they seek more accuracy.
