Combo La Grosse Blanche?

After reading the following (http://coticule.be/the-cafeteria/topic/1285.html?page=2)

La Grosse Blanche of course does exist as a natural combination version, but I've not yet seen one. I know from Maurice La Grosse Blanche does not exist at the depth they're currently mining, so unless they start mining back at higher levels farther to the East, I don't expect to see many Grosse Blanches. (The same thing is true for La Grosse Jaune)
Paul is right that the spots do look like those found on some La Grosse Blanches, but they usually have a brown hue.

I was curious if the following is a combo La Grosse Blanche:

It's a possibility.

Does it darken after prolonged exposure to (sun)light? Does the slurry have a distinct soapy texture?

Kind regards,
Bart.

I haven't exposed it to sunlight, so I cannot answer if it darkens. There were several patches of a darker rust color on the sides of the yellow coticule when I got the stone. Out of curiosity I lightly sanded them to see what would happen - the sanding removed the rusty color. The last shot of the "toe" shows a tiny spot of the rust color where the coticule meets the BBW. And yes, the slurry on this stone does have a more slippery/soapy feel than my La Dressante or Les Lat.

This stone also came with much more rounded (softer) edges and corners then other stones I have purchased, which I find curious Note: it does have one straight side because I trimmed the width down to 40mm with a hacksaw and haven't had time to round out the cut side to match the rest of the stone.

Thank you for the information, Bart.
