As a result of a thread elsewhere I checked my "Aircraft_Inventory" for my multiplayer folder and found that a whole heap of stuff had not been installed.
There is a download of Ray's 2019 planesets available, but for some reason I had not downloaded it or installed it on my PC.
There is some excellent material in it which will be added to your "Aircraft_Inventory" and "Planesets" folders.

Ray's 2019 planes and planesets

Download the 7-zip self installer and run it in your "UAW160" and /or your "UAW160 Multiplayer" folder.
AFAIK nothing will be overwritten

Thanks Jelly and must also add Ray will be popping it in a bit later

Thanks to Jelly and Ray.
