What affects the value of Unity Model S6 Spotlight?

• The condition of the chrome plating, specifically looking for signs of pitting, peeling, or 'road rash' from years of use.

• Completeness of the assembly, including the original mounting hardware and the interior pistol-grip.
• Historical provenance, such as evidence the light was originally installed on a specific emergency or luxury vehicle.

How to Identify Unity Model S6 Spotlight?

• Check for the 'Unity' brand name and 'Model S6' designation stamped directly into the chrome housing or the base of the handle.
• Verify the presence of the original Bakelite interior control handle, which should operate the light's rotation smoothly.
