History and evolution of the 5RV facing?

I recently got a Vandoren Diamond Perfecta 5RV mouthpiece in pristine condition. It's completely original and unaltered, a beautiful example of its kind. I play-tested it and it plays with a sweet, focused sound with very little effort.

After measuring the facing, I was very surprised. I made a very detailed measurement, but considering the more or less standard feelers (.0015, .010, .024, .034) it's: 32+, 20+, 10, 4, and the tip is 1.01 mm. So it's short and closed, compared to any other facing in the current Vandoren lineup. Maybe the closest one would be the long-discontinued (but excellent) 3UD.

This is very different from more modern examples of any 5RVs! They usually measure around a 37-38 facing length and 1.06-1.07 tip. My questions are:

- What was the point when Vandoren decided to completely change this facing under the same name?

- Why did VD decide to use the same facing designation when the measurements were changed completely?

- Do you have other examples of original Perfecta 5RVs with facing measurements (at least tip + facing length)?

I'm excited to hear your thoughts on this.

Mark
