Schaken, the old man here. I'm in my 70s and have all of your FO4 power armor mods and they are great !!
Very good, !! Way back when I was more healthy I skinned a lot of train engines and boxcars for Train Sim
Anyway I wanted to mention to you the third T-51 power armor underwater out from the Harbor Grand Hotel in Far Harbor.
Tinting the Red Vim to Blue for the Quartz version would make a great add on.
If I could see I would give it a shot myself, but my time is short and what little skill I did have has failed me.
Changing just the Red to Blue would by far the easiest way to do it
If you would consider doing it , I would try and give as much help and assistance as I could
