Color roundies in motels

[old_tv_nut]

browsing old postcards at the antique market today, I was surprised to find three that showed motels with color roundies installed. After all, they were expensive, and required isntallation and service at a rate not reduced until the advent of the ubiquitous 19-inch rectangular table model.

Some folks here might help by exercising their knowledge of cabinet designs and control placements to identify these models.
