Actually this collection recently discovered in Merrie Olde Englande should rightly be sent in its entirety back to the States, perhaps to the NRA for redistribution to the membership in partial repayment for all the personal weapons we sent to the Brits at the beginning of WWII. You will remember that the British government confiscated and destroyed the lot of them as soon as they perceived the local citizens as a greater threat to their jobs than the Wehrmacht.
Think about it: Join the NRA and get one raffle ticket for the firearm of your choice for each year of membership you buy. Life members will get tickets based on the actuarial estimate of their remaining years, 85 minus your age for men, and 86 minus your age for women or whatever the current numbers are.
Offer valid in all states covered by the U.S. constitution.
