@farmerman,
They appear to be aluminum cases, embossed. I forgot to see if the bottling works is on it. Likely Houston, because all of the bottles are Houston. On the bottles bottoms with one case Houston Texas is away from the center, with a c directly in the middle. The others have Houston Teas in larger letters, no c. They are 6 1/2 ounces. Most have the caps but all are rusty. There are just five bottles in one case, with what looks to be a 6 oz or less Grapette bottle in the last hole.
