I'm confused (this happens often)...
What is the difference between the 14B ST/ 6B ST and their SST version.
I rarely see mention of these pieces. Where these made only for a very short time? Are they basically the same as the SST but produced prior to the across the board redesign and name change?
Just a general description of any differences will be fine. Much more will be lost on me.

Thanks in advance,
- Jim
