From the release:
Finger and Toe Models announces the release of the 28mm PDF El Presidio de Leon, an adobe fort inspired by the presidios of colonial California, but usable for any mud fort from the Dark Ages through near future. El Presidio comes with six different wall modules for variety, a gate with watchtower, a ramp, and a demilune for outer works. While El Presidio de Leon is a stand alone model set, it is textured and styled to fit with the Finger and Toe Adobeville sets.
Remember, every Finger and Toe model comes with SMOOSH ASSURANCE: if ya’ll smoosh your El Presidio de Leon, a new set waits your summons from hard drive and printer.
