Call them meters if you will, but the design is Scott listed as CVP.

Edit: Question for JWL, are these printed on the envelopes, or on a label attached to the envelope? Maybe eyeonwall is right that these are meters using the same standard Pitney Bowes design used on the CVP machines that print the labels.
Edit2: Yeah, I think eyeonwall is right. The CVP75 labels are printed in black with a pink stripe at the right, just like the picture in the Scott catalog. the "just pink" ones that you ask about are probably ordinary meters just like are used at thousands of companies around the world.
