Please Help Identify this Cola Bottle

Please help me identify this bottle. It was found, as is, under a house
in Austin, Texas. It appears that it has never been opened. The cap has one rust hole that has leaked some of the contents.
There are no markings anywhere on the bottle other than the brand, which is "KING'S COLA" Under that is "TRADE-MARK"

The bottle has the appearance of hand blown. It's a little twisted and lots
of bubbles as you can see in the photos.

I've looked, and with my limited computer skills, I have come up zero
information.

Any help would be greatly appreciated. Thanks
