Well, Ray...I think clarnibass and Karl brought me full circle to your original comment!
Comparing joints more closely (as Karl suggested), combined with matching up the tone holes/etc., and with the encouragement of clarnibass...I'm convinced you have all helped me resolve this issue.
Comparing joint to joint, the tone holes all match (nearly) up to my other Bb models - with small differences between them, but generally very close. That extra length of the upper joint is entirely above the register vent, so I think it is probable that the barrel was somewhere in the neighborhood of 50mm instead of the standard 65-67mm barrels my other simple systems of the era have.
So, now the journey begins to find a 50mm barrel for testing. I hate to buy a bunch of barrels while trying to find the correct length, but I'm not sure how else to proceed. Do any of you know of resources a person could use for this type of trial-and-error work? (If nothing else, I might just go out and try to turn something out on my lathe to provide a proof of concept...though my lathe equipment leaves a lot to be desired for this type of work!)
Thanks to all of you...not only did you help me to find what I feel is the right answer, but you helped me understand the troubleshooting process and resolution along the way! I truly appreciate the time and thought you all put into this on my behalf!
