A number of "US" marked SAAs were returned either to the Colt factory or to the Springfield Armory, where they were altered and refinished. These revolvers have 5.5" barrels and any combination of mixed serial numbers. They were remarked by inspectors of the era. They have case colored frame, blued cylinder and barrel. Some have been noted all blued within this variation. This model, as with other military marked Colts, should definitely be authenticated before purchase. Some of these revolvers fall outside the 1898 antique cutoff date that has been established by the government. In our experience are not quite as desirable to investors. They are generally worth approximately 20 percent less. Add a 50 percent premium for specimens marked "New York State Militia". These have 7.5" barrels and only 800 are documented in Colt records. Be sure to obtain documentation from the factory for these models. Premium for rare artillery models with matching serial numbers.
