I recently came into the ownership of this beautiful colt. I have done some research and found that it was issued to the British Royal Air Force during WWI. Does anyone have any other info they might be able to give me in this weapon? Value etc...

I recently cam into the ownership of a beautiful Colt. It is a 1911 Colt .455 Eley and it in Nickel. It is a beautiful gun and I am trying to find out what it may be worth. I have done some research but don't know a lot about it as of yet. Does anyone have any information on this gem?
