Do You Recognize These Housing Plates?

We need your help understanding these plates from the Paraiso Housing Office. What was their function? What do S/R, M/R, and M/T stand for? Were the holes used to hold keys? Would something be written in the white spaces?

    My father, Col Ed Jennings, Corp of Engineers, was stationed in the CZ for 4 years in the mid 1950’s. We lived in Diablo.

    Dad’s project was to prevent Contractors Hill from slipping into the Canal. I have inherited many photos of the job site and articles that might be of interest to the Museum.

    Please let me know. Thanks David Jennings (703) 862-7069
