Now it's obvious that this was a Cauvet's patent, but it just can't be a CD 126. The piece is small, but includes both the top and bottom wire ridge, so it's pretty easy to determine the CD. All the CD 126's I've seen have roundish ridges, and this piece has both sharply defined upper and lower ridges like a CD 102 Brookfield. I've included the 102 Brookfield in the picture for reference. Any more help would be great.
