Le Grelot also made stuff like that, which is a bit less common: http://straightrazorplace.com/srpwiki/index.php/Le_Grelot_"No_5"_7/8
Interesting. Mine and I'm sure Ray's are a "55" and I see that the Le Grelot has a "5", were Le Grelot making the same razor for either one another? Or was just just to compete with each others line?
