We do have access to a wide variety of leather. One can send an email with the details of the desired type and we will revert with available options. Takes about 8 weeks currently. We do stock the black calf that this jacket was made from.
Whenever I write to them, they point me to the Indian resellers who mark the fabrics up by a few hundred percents. If anyone has a contact with the right sales people at Alumo, Albini etc, a PM will be helpful.
