How/where might one contact a painter of a downloaded skin for assist or to request modifications for personal use? At this point in time I would particularly like to find Paul Craig concerning his work on a Beechcraft B60 Duke for FSX SE.
Check the read-me and see if his email is in it.
There are others who have made textures for that aircraft, you can see if they have an email in their download.
In this particular case, Paul's name is noted in each texture's description. But I find no contact info for anyone in the downloaded folders.
Check all the work he's done.
If his email isn't listed then email the designer of the aircraft he worked on, he should know Paul's email.
Try him email@example.com
