This Collins Horizontal Situation Indicator was removed from an IAI Westwind 1124 during a full avionics and cockpit teardown. The unit is offered in as-removed, untested condition and is suitable for repair, overhaul, core inventory, training, or simulator use.

The face shows typical age-related wear, including bezel flaking consistent with legacy Collins instruments. The glass is intact with some surface spotting. All markings remain readable, and the rear connectors appear intact.
