What is a singer 1911 45 pistol worth?

Singer made only 500 serial numbered weapons for the military. Starting serial was 800001 ending was 800500. An unknown amount were made for Singer employees, but they were not serial numbered. I have seen them go for as little as $3500.00 for guns in about 60 Percent condition to $100,000.00 for guns in 95% condition. There are only about 150 known to still exist. I have a singer 1911 45 caliber pistol serial #s800351 in Excellent condition ? call Bill at 352 279 7068
