Yes they do exist & I have the Runway 30 set for a 144 scale 747-200. I bought it over 10 years ago, but it has been looked after being stored flat at room temperature so should be in good condition. It is a big sheet with all cheatlines, doors etc. I would be interested in parting with it for a fair price as I did plan to use it myself, but time being thine enemy I may never get round to it. Hannants (as already suggested) still have available a Liveries Unlimited 737-200 set in 144 scale & I believe Liveries Unlimited also made a set for the 767-200, but not now listed anywhere.
If you are interested post a reply.
