Cue case
Mr. Rodcar,
If my memory serves me correctly, I do believe that the outer fabric on this case, is actually Bolivian Goat Udder Skin, which is normally blessed by 3 Priests and 1 Rabi, for a minimum of 3 full moons. After the skinning process, the hide would be smoked over a pile of used car tires for 4.5 days, then hung in the sun to ferment, the only tanning process they had at the time. After the hides were cured, the female clansfolk would chew, or gum off the remaining hair, woodticks, or any other foreign matter.
The locals have always claimed that no goats were hurt, or killed during this process. Must be one hell of a road rash, wow.
These are virtually impossible to find in this day and age. This type case was originally used to smuggle poppy seeds out of the homeland, this occurred mostly during the 60's and early 70's, thus no chalk residue found in your case..
As always, good luck with the sale. Just figured a little more knowledge couldn't hurt your chances.
