La grosse jaune I had one it was number 21 in the coticule vault among the slower coticule. Now I remember it very well as I learned to hone with it . I struggled at first but I remember when I hit the sweet spot with it and it was the smoothest shave I had . I remember messaging Bart about it and thinking this beat a cromox paste. Should never of sold that coticule it was a great shaver. I just received ten coticule a from Maurice and I have feeling I have a three lgj . The ones I suspect are lgj are very thick fat slices yellowish and when whet look dotty.
