BTW, ...I'm not in favor of stretching the action hanging in this manner. I
merely described what I though might be the special advantages of a high
ratio action


And, in fact, I agree with you.  As I mentioned in another post, my
preference is for 5.75 and an accompanying SW/BW combo that delivers the
FW's comfortably below maximums.  Moreover, I prefer to achieve that with a
17 mm knuckle to keep the friction at that point from going too high.

I'm sorry that the PTG didn't find reason to fund Birkett's project.  It
seems like a logical next step.
