Rezso confirmed to me that they will not be receiving any more Ilcea leathers. But the good news is that they have found an alternate supplier in France. He said the new supplier is where JLP is currently sourcing some of their leather. I wonder if this is where the "misty calf" comes from or perhaps it is the "ultra calf" (examples of this ultra calf are under the "By Request" section of the website.
The third color is a deep navy blue. It appears that the new supplier has this color as well as I had a boot ordered in it.
Yes, it's Tannery Haas in Strasbourg. It was mentioned above in this thread, that John Lobb switched from Ilcea to another supplier for their museum calf about a year ago, and I think that since then they buy it from Haas. Also Zonta in Italy makes a museum calf-like leather, and know Rezso has contacted them as well as a back up for Haas. Hopefully Vass will be able to get some badges already early fall, and everything will be great again.
