I had several Double Eagles including 3 10MM First Editions.
I still have one of the 10MMs and my Light weight Officers 45.
The 10MM First Editions were serial numbers 737, 747 and 757. I like numbers
For a time I carried the LW Officers 45 in an ankle rig. It fits the 469 holsters just fine. In fact my ankle rig and DE are sitting next to my bed right now.
I had a DE Commander 45, but it was stolen with my Suburban back in 96
The Double Eagle is mostly a copy of the Secamp conversion. It was not a bad pistol, especially for a Colt guy
The magazines are standard 1911
I wish I had bought the one I saw in 38 Super, but way back then I had less disposable income and had to pass
At the asking price I would be a buyer.
However, unless it is unfired since leaving the factory and complete in it's original packaging, I do not think it is much of a collectible. . . YET. Give it another 20-30-50 years
