Diebold / Herring-Hall-Marvin (HHM) \"5-Star Constellation\" bank vault door. For Sale

Diebold 5 Star Constellation Originally engineered and patented under the legendary Herring-Hall-Marvin Safe Co. (HHM) line, it continued production under Diebold after Diebold acquired HHM in 1959. In technical reference manuals (such as Dave McOmie\'s vault door guides), it is classified directly as the Diebold 5-Star Constellation (or HHM / Diebold Constellation).
Exterior Architecture: The signature modern mid-century aesthetic—vertical division stripe down the center, offset rectangular dial/time-lock box with the star cluster, and a central through-hole for the primary operating hub—defines this specific series. 
Rear Electro-Hydraulics: The power-pack assembly on the rear door face (Image 4) is the factory electro-hydraulic bolt-throw and compressive seating mechanism used on these units to cycle the massive multi-bolt carriage (Image 3) without requiring pure manual muscle to engage the frame.Located in Houston. Local pick up only. All the parts were there I believe but needs reassembly and cannot confirm the hydraulics are in working condition. As is $4000.
