Reawakening this thread...as I have a few of these. It seems that as late as 1999, the V40s were still very similar to the 7214s. I have attached a chart of bore measurements; I just measured the ends...but did so repeatedly and with calibration so I am convinced the small differences are real, but probably just manufacturing variation.

The main difference between the 7214 and the V40 seems to be the gold (plated?) springs on the V40. Both of these come in two variations:

The lyre logo 7214 and the "C" serial V40 have metal 'button' inserts for flat springs (trill key, etc), and do NOT have the PRAG

The V logo 7214 and the "D" serial V40 have flat recesses machined into the plastic for the flat spring seats (no metal) and DO have the PRAG.

There are a few other minor cosmetic differences. The V Logo 7214 is well-used but well-maintained and, while I was skeptical about the springs bearing on plastic, I could not see any wear other than light polishing under the springs.

The only thing that I learned from the bore measurements is that there is substantial variability in the barrel dimensions. It appears that these barrels are shaped by hand from the curve measurements. I have attached also the barrel taper curves...I can assure you that my measurements are much more accurate than the production of the curves. I don't see that there is barrel design variation according to either vintage or 7214 vs V40. These all play a little different, so I may do some A/B rotation. I ordered a few extra vito barrels from Ferrees surplus and may play around with bore matching them to the uppers.
