The star or the & in that location, are the most common stamps used by Colt to indicate the gun has been back to the factory for some work, could be refinishing, part replacements, rebuild, etc.
If your gun was refinished, it will also have a 3 or 4 gigit "drawer" # on all major parts stamped in inconspicuous locations; under grips, or ejec housing, etc.
When the star and & were used is unclear, but for many decades at least.
