Western Airlines Lockheed L188 Electra Model

I am interested in purchasing a Western Airlines Raise Up lockheed Electra model--preferably original with original stand but am open to a good restoration. Any feedback that anyone can provide as to the likelihood of my locating one and any thoughts you might have as to whether I should give consideration to the Gary Field's casting of the Western Electra and how it compares to the Raise Up would be greatly appreciated. I am not familiar with the finer detail differences between the two. Many thanks.
