Bagger,
As I recalled the Audio tapes when Homer was asked. Why the Swinger can only be Accumulator 4 2 3 and not 4 barrel? His answer is there is no point?
Part of my Video message is trying to explain my understanding of that.
====o=====
Another point I am trying to make is how does that difference affect Other parts of the components.
We don't get into that required Alignment( or position) just because its compatible ... its also because of how the Forearm is Aligned , loaded, and supported in the first place. Those alignment becomes, an effect.
Have some fun and think about it.
