I'm thinking about letting go of this Laureat fp/bp set, but hesitate because I've never bothered to figure out what the color or model series is called. Kirkel has them pictured, but no name. I've seen them only one other place - a French sales catalog - where they were identified as South Seas Marble. I have a similar one in red (fountain pen only). Translucent section and blind cap, chrome trim, compass rose on caps. Does anyone know who they are? Are they rare? Are they collectible or just another of the many nice Laureat colors? Thanks, Craig
