I have twice posted Learjet queries on the forum, seeking assistance, and forum users have successfully come to my aid....so I try once more please:

I have a photograph of Learjet 25 N858GM at Tucson in 1973, but cannot find the c/n for this aircraft. Can anyone help please so that I can trace a profile or create one?

Peter

Now that is what I call a speedy reply - many thanks Nick. Once again this shows how useful the forum can be. Much obliged.
