Is it really your dream gun or are you after the damascus steel frame?
Seems like possibly one could commission a damascus 1911 frame (or some other ???) from a shop here in the states for a true one of a kind purchase.
OTOH, if it is your dream go for it. Permission granted only under the condition of you MUST shoot it. AND you MUST post pics, lots of them, and a range report for your friends here at TFL.
