It's uncertain if Indiana Bridge built any more of these "High Triangular" trusses besides Kidner and Peterson Ford in Indiana, and the one over Seven Mile Creek in Preble County, Ohio. But it has been documented that IBC erection crews complained about the trusses and how difficult they were to assemble.
Yes, they are essentially Pegram trusses in configuration, but they are often not labeled as such because they are not quite exactly following the Pegram patent and Indiana Bridge Co. apparently had their own name for their design. Extremely rare and significant.
This was a particularly interesting structure. These High-Triangular trusses in Indiana and Ohio seem to be some type of cross between a Warren and a Parker Truss, much like a Pegram Truss.
