Geodetic Control Diagrams

I have a very limited collection of geodetic control diagrams (and their associated keys) for the PA/NY/NJ area. Due to their limited usefulness and large form factor, I’ve decided not to scan them for this site, but I will scan on demand for anyone who would like a copy. Please contact me with your request.
