That was my question too. I did it once from Pakistan.
ATF Regulation:
If the firearm you intend to import is an antique firearm and was manufactured in or before 1898, you or an FFL do not have to submit an ATF Form 6 to ATF; however, you must be able to prove to CBP that it was manufactured during that period. If you ship the antique firearm, be sure the package includes the required documentation. CBP will accept a certificate of authenticity or bill of sale with the year the antique firearm was manufactured as proof of age. If the firearm was manufactured after 1898, an FFL must submit the ATF Form 6 to ATF for authorization to import the firearm. If the antique firearm is at least 100 years old or more and you can provide proof of age, the firearm will be eligible for duty-free treatment under the antique provision in the Harmonized Tariff Schedule.
However, getting out of UK seems to be the problem:
As far as the process of shipping from the United Kingdom, there is no legal way to ship a weapon out of the United Kingdom without using a licensed shipping agent.
United Kingdom rules and regulation for firearms require a number of documents and require that the shipping agent to complete prior to the weapon being shipped to the United States.
