The first Tournalaid community was established in Vicksburg, Mississippi. The second community was located in Longview, Texas; there was much press coverage on this event. Other communities were established in Muroc, California and Yuma, Arizona. Papers from the LeTourneau archive refer to houses that were built in Los Angeles, California and Corpus Christi, Texas; I have yet to locate these communities.
Other communities were established in Beer Sheva, Israel; Argentina and Brazil.
The photo shows Tournalaid houses that are suspected to be in South America, either Argentina or Brazil. The basic single cast concrete structure was added to with a hand-laid parapet detail. Note that some of the houses are missing the parapet and some are being created.
If you have information pertaining to these communities or others, I would appreciate your input.
