Well that sure changes things. They made like a quarter million 1851's.
I'll give ya' a hundreds bucks for it, assuming it's in good condition
and you are willing to deliver it.
Seriously----don't do anything to it. Don't "clean it up", don't try
to take it apart, NOTHING.
Get it to a good reputable appraiser that specializes in old Colts.
See if the Colt factory can provide a "Factory Letter" on it.
Both of these will cost you some bucks, but it's money well
Depending on condition and provenance a 1851 Navy can have a value
from a few hundred to many thousand.
